121-522: In the International Phonetic Alphabet , implosives are indicated by modifying the top of a letter (voiced stop) with a rightward-facing hook: ⟨ ɓ ɗ ᶑ ʄ ɠ ʛ ⟩. During the occlusion of the stop, pulling the glottis downward rarefies the air in the vocal tract. The stop is then released. In languages whose implosives are particularly salient, that may result in air rushing into the mouth before it flows out again with

242-483: A pitch trace on a musical scale . Beyond the letters themselves, there are a variety of secondary symbols which aid in transcription. Diacritic marks can be combined with the letters to add tone and phonetic detail such as secondary articulation . There are also special symbols for prosodic features such as stress and intonation. There are two principal types of brackets used to set off (delimit) IPA transcriptions: Less common conventions include: All three of

363-561: A writing system , built huge pyramids and temples , had a complex calendar , and developed the concept of zero around 400 CE. The first recorded European references to North America are in Norse sagas where it is referred to as Vinland . The earliest verifiable instance of pre-Columbian trans-oceanic contact by any European culture with the North America mainland has been dated to around 1000 CE. The site , situated at

484-532: A conflicting use to delimit prosodic transcription within the Voice Quality Symbols , which are an extension of IPA used in extIPA, but are not otherwise used in IPA proper. Other delimiters sometimes seen are pipes and double pipes taken from Americanist phonetic notation . However, these conflict with the pipes used in basic IPA prosodic transcription. Other delimiters are double slashes, –

605-616: A dental–retroflex distinction in its plosives, with /b d ɖ  ɟ ɡ/ , the contrast is neutralized in the implosives. A contrastive retroflex implosive /ᶑ/ may also occur in Ngad'a , a language spoken in Flores , Indonesia , and occurs in Wadiyara Koli , a language spoken in India and Pakistan where it contrasts with the voiced alveolar implosive /ɗ/ . More examples can be found in

726-580: A group of French and English language teachers, led by the French linguist Paul Passy , formed what would be known from 1897 onwards as the International Phonetic Association (in French, l'Association phonétique internationale ). The idea of the alphabet had been suggested to Passy by Otto Jespersen . It was developed by Passy along with other members of the association, principally Daniel Jones . The original IPA alphabet

847-523: A lowering of the glottis by some individuals, occasionally to the extent that they are noticeably implosive, but no language is known where implosion is a general characteristic of such sounds. The attested voiced implosive stops are the following: There are no IPA symbols for implosive fricatives, and no confirmed cases of implosive fricatives or affricates. Implosive affricates are occasionally reported, but further investigation typically reveals that such sounds are either stops or not implosive. For example,

968-452: A mix of IPA with Americanist phonetic notation or Sinological phonetic notation or otherwise use nonstandard symbols for various reasons. Authors who employ such nonstandard use are encouraged to include a chart or other explanation of their choices, which is good practice in general, as linguists differ in their understanding of the exact meaning of IPA symbols and common conventions change over time. Many British dictionaries, including

1089-597: A part of Denmark) and Mexico classified as Latin American). It is unknown with certainty how and when first human populations first reached North America. People were known to live in the Americas at least 20,000 years ago, but various evidence points to possibly earlier dates. The Paleo-Indian period in North America followed the Last Glacial Period, and lasted until about 10,000 years ago when

1210-664: A period of mountain building called the Laramide orogeny , between 80 and 55 mya. The formation of the Isthmus of Panama that connected the continent to South America arguably occurred approximately 12 to 15 mya, and the Great Lakes (as well as many other northern freshwater lakes and rivers) were carved by receding glaciers about 10,000 years ago. North America is the source of much of what humanity knows about geologic time periods. The geographic area that would later become

1331-590: A powerful earthquake killed seven people in 2009. Volcanic eruptions are common in the region. In 1968, the Arenal Volcano , in Costa Rica, erupted and killed 87 people. Fertile soils from weathered volcanic lavas have made it possible to sustain dense populations in agriculturally productive highland areas. Central America has many mountain ranges ; the longest are the Sierra Madre de Chiapas ,

1452-695: A row left out to save space. In the table below, a slightly different arrangement is made: All pulmonic consonants are included in the pulmonic-consonant table, and the vibrants and laterals are separated out so that the rows reflect the common lenition pathway of stop → fricative → approximant , as well as the fact that several letters pull double duty as both fricative and approximant; affricates may then be created by joining stops and fricatives from adjacent cells. Shaded cells represent articulations that are judged to be impossible or not distinctive. Vowel letters are also grouped in pairs—of unrounded and rounded vowel sounds—with these pairs also arranged from front on

1573-611: A seven-way contrast among bilabial stops, /pʰ p ƥ bʱ b ɓ m/ , and its alveolar stops are similar. The voiceless velar implosive [ ƙ ] occurs marginally in Uspantek and /ʠ/ occurs in Mam , Kaqchikel , and Uspantek . Lendu has been claimed to have voiceless /ƥ ƭ ƈ/ , but they may actually be creaky-voiced implosives. The voiceless labial–velar implosive [ƙ͜ƥ] also may occur in Central Igbo. Some English speakers use

1694-465: A slightly different airstream mechanism, purely glottalic ingressive. The glottis is closed so no pulmonic airstream is possible. The IPA once dedicated symbols ⟨ ƥ ƭ 𝼉 ƈ ƙ ʠ ƙ͜ƥ ⟩ to such sounds. These were withdrawn in 1993 and replaced with a voiceless diacritic, ⟨ ɓ̥ ɗ̥ ᶑ̥ ʄ̊ ɠ̊ ʛ̥ ɠ̊͜ɓ̥ ⟩, though ⟨ ƥ ƭ ƈ ⟩ remain in Serer orthography. Some authors disagree with

1815-452: A variety of foreign languages. They are also taught by vocal coaches to perfect diction and improve tone quality and tuning. Opera librettos are authoritatively transcribed in IPA, such as Nico Castel 's volumes and Timothy Cheek's book Singing in Czech . Opera singers' ability to read IPA was used by the site Visual Thesaurus , which employed several opera singers "to make recordings for

1936-540: A variety of reactions, including curiosity, trading, cooperation, resignation, and resistance. The indigenous population declined substantially following European arrival, primarily due to the introduction of Eurasian diseases, such as smallpox , to which the indigenous peoples lacked immunity, and because of violent conflicts with Europeans. Indigenous culture changed significantly and their affiliation with political and cultural groups also changed. Several linguistic groups died out , and others changed quite quickly. On

2057-419: A voiceless velar implosive [ƙ] to imitate the "glug-glug" sound of liquid being poured from a bottle, but others use a voiced implosive [ɠ] . Symbols to the right in a cell are voiced , to the left are voiceless . Shaded areas denote articulations judged impossible.

North America is bordered to the north by the Arctic Ocean , to the east by the Atlantic Ocean , to the southeast by South America and the Caribbean Sea , and to the west and south by the Pacific Ocean . The region includes the Bahamas , Bermuda , Canada , the Caribbean , Central America , Clipperton Island , Greenland , Mexico , Saint Pierre and Miquelon , Turks and Caicos Islands , and

2299-665: Is a very large continent that extends from north of the Arctic Circle to south of the Tropic of Cancer . Greenland, along with the Canadian Shield , is tundra with average temperatures ranging from 10 to 20 °C (50 to 68 °F), but central Greenland is composed of a very large ice sheet. This tundra radiates throughout Canada, but its border ends near the Rocky Mountains (but still contains Alaska) and at

2420-493: Is an alphabetic system of phonetic notation based primarily on the Latin script . It was devised by the International Phonetic Association in the late 19th century as a standard written representation for the sounds of speech . The IPA is used by lexicographers , foreign language students and teachers, linguists , speech–language pathologists , singers, actors, constructed language creators, and translators . The IPA

2541-524: Is an ancient craton which forms the geologic core of North America; it formed between 1.5 and 1.0 billion years ago during the Proterozoic eon. The Canadian Shield is the largest exposure of this craton. From the Late Paleozoic to Early Mesozoic eras, North America was joined with the other modern-day continents as part of the supercontinent Pangaea , with Eurasia to its east. One of

2662-421: Is designed for transcribing sounds (phones), not phonemes , though it is used for phonemic transcription as well. A few letters that did not indicate specific sounds have been retired (⟨ ˇ ⟩, once used for the "compound" tone of Swedish and Norwegian, and ⟨ ƞ ⟩, once used for the moraic nasal of Japanese), though one remains: ⟨ ɧ ⟩, used for the sj-sound of Swedish. When

2783-483: Is designed to represent those qualities of speech that are part of lexical (and, to a limited extent, prosodic ) sounds in oral language : phones , intonation and the separation of syllables . To represent additional qualities of speech—such as tooth gnashing , lisping , and sounds made with a cleft palate —an extended set of symbols may be used. Segments are transcribed by one or more IPA symbols of two basic types: letters and diacritics . For example,

2904-495: Is elected by the membership – for further discussion and a formal vote. Many users of the alphabet, including the leadership of the Association itself, deviate from its standardized usage. The Journal of the IPA finds it acceptable to mix IPA and extIPA symbols in consonant charts in their articles. (For instance, including the extIPA letter ⟨ 𝼆 ⟩ , rather than ⟨ ʎ̝̊ ⟩, in an illustration of

3025-546: Is in present-day Panama at the Darien Gap on the Colombia -Panama border, placing almost all of Panama within North America. Alternatively, some geologists physiographically locate its southern limit at the Isthmus of Tehuantepec , Mexico, with Central America extending southeastward to South America from this point. The Caribbean islands, or West Indies, are considered part of North America. The continental coastline

3146-648: Is long and irregular. The Gulf of Mexico is the largest body of water indenting the continent, followed by Hudson Bay . Others include the Gulf of Saint Lawrence and the Gulf of California . Before the Central American isthmus formed, the region had been underwater. The islands of the West Indies delineate a submerged former land bridge , which had connected North and South America via what are now Florida and Venezuela . There are several islands off

3267-654: Is needed to determine the true nature of these sounds. Implosives may occasionally occur phonetically in some European languages: For instance, in some northern dialects of Ingrian , intervocalic bilabial stops may be realised as the implosive [ɓ] or [ɓ̥] . Fully voiced stops are slightly implosive in a number of other languages, but this is not often described explicitly if there is no contrast with modal-voiced plosives. This situation occurs from Maidu to Thai to many Bantu languages , including Swahili . Sindhi and Saraiki have an unusually large number of contrastive implosives, with /ɓ ᶑ  ʄ ɠ/ . Although Sindhi has

3388-528: Is not always accessible to sight-impaired readers who rely on screen reader technology. Double angle brackets may occasionally be useful to distinguish original orthography from transliteration, or the idiosyncratic spelling of a manuscript from the normalized orthography of the language. Pipes are sometimes used instead of double angle brackets to denote the distinct allographs of a grapheme that are known as glyphs . For example, print | g | and script | ɡ | are two glyph variants of

3509-561: Is part of North America geographically. In a geologic sense, Bermuda is not part of the Americas, but an oceanic island that was formed on the fissure of the Mid-Atlantic Ridge over 100 million years ago (mya). The nearest landmass to it is Cape Hatteras , North Carolina . However, Bermuda is often thought of as part of North America, especially given its historical, political and cultural ties to Virginia and other parts of

3630-707: Is the Morrison Formation of the western U.S. Canada is geologically one of the oldest regions in the world, with more than half of the region consisting of Precambrian rocks that have been above sea level since the beginning of the Palaeozoic era. Canada's mineral resources are diverse and extensive. Across the Canadian Shield and in the north there are large iron, nickel, zinc , copper, gold, lead, molybdenum , and uranium reserves. Large diamond concentrations have been recently developed in

For this reason, most letters are either Latin or Greek , or modifications thereof. Some letters are neither: for example, the letter denoting the glottal stop , ⟨ ʔ ⟩, originally had the form of a question mark with the dot removed. A few letters, such as that of

3993-454: The Age of Discovery and the early modern period . Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples , enslaved Africans , immigrants from Europe, Asia, and descendants of these respective groups. Europe's colonization in North America led to most North Americans speaking European languages, such as English , Spanish , and French , and

4114-519: The Archaic period began. The classic stage followed the Archaic period, and lasted from approximately the 6th to 13th centuries. Beginning in 1000 AD, the Norse were the first Europeans to begin exploring and ultimately colonizing areas of North America. In 1492, the exploratory voyages of Christopher Columbus led to a transatlantic exchange , including migrations of European settlers during

4235-567: The Bering Strait during the Early-Middle Holocene . Prior to the arrival of European explorers and colonists in North America, the natives of North America were divided into many different polities, ranging from small bands of a few families to large empires. They lived in several culture areas , which roughly correspond to geographic and biological zones that defined the representative cultures and lifestyles of

The continent can be divided into four great regions (each of which contains many subregions): the Great Plains stretching from the Gulf of Mexico to the Canadian Arctic ; the geologically young, mountainous west, including the Rocky Mountains , the Great Basin , California , and Alaska ;

4598-568: The Cordillera Isabelia , and the Cordillera de Talamanca . Between the mountain ranges lie fertile valleys that are suitable for the people; in fact, most of the population of Honduras, Costa Rica, and Guatemala live in valleys. Valleys are also suitable for the production of coffee, beans, and other crops. The indigenous peoples of the Americas have many creation myths , based on which they assert that they have been present on

4719-465: The East Coast to eastern North Dakota , and stretching down to Kansas , is the humid continental climate featuring intense seasons, with a large amount of annual precipitation, with places like New York City averaging 50 in (1,300 mm). Starting at the southern border of the humid continental climate and stretching to the Gulf of Mexico (whilst encompassing the eastern half of Texas)

4840-466: The Handbook recommended against their use, as cursive IPA is "harder for most people to decipher". A braille representation of the IPA for blind or visually impaired professionals and students has also been developed. The International Phonetic Alphabet is occasionally modified by the Association. After each modification, the Association provides an updated simplified presentation of the alphabet in

4961-460: The Hebrew alphabet for transcription of foreign words. Bilingual dictionaries that translate from foreign languages into Russian usually employ the IPA, but monolingual Russian dictionaries occasionally use pronunciation respelling for foreign words. The IPA is more common in bilingual dictionaries, but there are exceptions here too. Mass-market bilingual Czech dictionaries, for instance, tend to use

5082-570: The IPA extensions . In the IPA itself, however, only lower-case letters are used. The 1949 edition of the IPA handbook indicated that an asterisk ⟨*⟩ might be prefixed to indicate that a word was a proper name, but this convention was not included in the 1999 Handbook , which notes the contrary use of the asterisk as a placeholder for a sound or feature that does not have a symbol. The IPA has widespread use among classical singers during preparation as they are frequently required to sing in

5203-620: The Inuit of the high Arctic arrived in North America much later than other native groups, evidenced by the disappearance of Dorset culture artifacts from the archaeological record and their replacement by the Thule people . During the thousands of years of native habitation on the continent, cultures changed and shifted. One of the oldest yet discovered is the Clovis culture (c. 9550–9050 BCE) in modern New Mexico . Later groups include

The more southern cultural groups of North America were responsible for the domestication of many common crops now used around the world, such as tomatoes, squash , and maize . As a result of the development of agriculture in the south, many other cultural advances were made there. The Mayans developed

5566-792: The Oxford English Dictionary and some learner's dictionaries such as the Oxford Advanced Learner's Dictionary and the Cambridge Advanced Learner's Dictionary , now use the International Phonetic Alphabet to represent the pronunciation of words. However, most American (and some British) volumes use one of a variety of pronunciation respelling systems, intended to be more comfortable for readers of English and to be more acceptable across dialects, without

5687-516: The United States . North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), representing approximately 16.5% of the Earth 's land area and 4.8% of its total surface area. It is the third-largest continent by size after Asia and Africa , and the fourth-largest continent by population after Asia, Africa, and Europe . As of 2021 , North America's population

5808-488: The first official name given to Mexico. North America includes several regions and subregions, each of which have their own respective cultural, economic, and geographic regions. Economic regions include several regions formalized in 20th- and 21st-century trade agreements, including NAFTA between Canada , Mexico , and the United States , and CAFTA between Central America , the Dominican Republic , and

5929-562: The voiced pharyngeal fricative , ⟨ ʕ ⟩, were inspired by other writing systems (in this case, the Arabic letter ⟨ ﻉ ⟩, ʿayn , via the reversed apostrophe). Some letter forms derive from existing letters: The International Phonetic Alphabet is based on the Latin script , and uses as few non-Latin letters as possible. The Association created the IPA so that the sound values of most letters would correspond to "international usage" (approximately Classical Latin ). Hence,

6050-458: The 1490s, building cities, putting the resident indigenous populations to work, raising crops for Spanish settlers and panning gold to enrich the Spaniards. Much of the indigenous population died due to disease and overwork, spurring the Spaniards on to claim new lands and peoples. An expedition under the command of Spanish settler, Hernán Cortés , sailed westward in 1519 to what turned out to be

6292-630: The Arctic, making Canada one of the world's largest producers. Throughout the Shield, there are many mining towns extracting these minerals. The largest, and best known, is Sudbury , Ontario. Sudbury is an exception to the normal process of forming minerals in the Shield since there is significant evidence that the Sudbury Basin is an ancient meteorite impact crater . The nearby, but less-known Temagami Magnetic Anomaly has striking similarities to

6413-651: The Caribbean islands. France took the western half of Hispaniola and developed Saint-Domingue as a cane sugar producing colony worked by black slave labor. Britain took Barbados and Jamaica , and the Dutch and Danes took islands previously claimed by Spain. Britain did not begin settling on the North American mainland until a hundred years after the first Spanish settlements, since it sought first to control nearby Ireland . The first permanent English settlement

Waldseemüller used the Latin version of Vespucci's name, Americus Vespucius, in its feminine form of "America", following the examples of "Europa", "Asia", and "Africa". Americus originated from Medieval Latin Emericus (see Saint Emeric of Hungary ), coming from the Old High German name Emmerich . Map makers later extended

6655-627: The Greek alphabet, though their sound values may differ from Greek. For most Greek letters, subtly different glyph shapes have been devised for the IPA, specifically ⟨ ɑ ⟩, ⟨ ꞵ ⟩, ⟨ ɣ ⟩, ⟨ ɛ ⟩, ⟨ ɸ ⟩, ⟨ ꭓ ⟩ and ⟨ ʋ ⟩, which are encoded in Unicode separately from their parent Greek letters. One, however – ⟨ θ ⟩ – has only its Greek form, while for ⟨ ꞵ ~ β ⟩ and ⟨ ꭓ ~ χ ⟩, both Greek and Latin forms are in common use. The tone letters are not derived from an alphabet, but from

6776-406: The IPA Handbook , the letters ⟨ c ⟩ and ⟨ ɟ ⟩ are used for /t͡ʃ/ and /d͡ʒ/ . Among the symbols of the IPA, 107 letters represent consonants and vowels , 31 diacritics are used to modify these, and 17 additional signs indicate suprasegmental qualities such as length , tone , stress , and intonation . These are organized into a chart; the chart displayed here

6897-492: The IPA have consisted largely of renaming symbols and categories and in modifying typefaces . Extensions to the International Phonetic Alphabet for speech pathology (extIPA) were created in 1990 and were officially adopted by the International Clinical Phonetics and Linguistics Association in 1994. They were substantially revised in 2015. The general principle of the IPA is to provide one letter for each distinctive sound ( speech segment ). This means that: The alphabet

7018-412: The IPA is used for broad phonetic or for phonemic transcription, the letter–sound correspondence can be rather loose. The IPA has recommended that more 'familiar' letters be used when that would not cause ambiguity. For example, ⟨ e ⟩ and ⟨ o ⟩ for [ɛ] and [ɔ] , ⟨ t ⟩ for [t̪] or [ʈ] , ⟨ f ⟩ for [ɸ] , etc. Indeed, in the illustration of Hindi in

IPA letters have been incorporated into the alphabets of various languages, notably via the Africa Alphabet in many sub-Saharan languages such as Hausa , Fula , Akan , Gbe languages , Manding languages , Lingala , etc. Capital case variants have been created for use in these languages. For example, Kabiyè of northern Togo has Ɖ ɖ , Ŋ ŋ , Ɣ ɣ , Ɔ ɔ , Ɛ ɛ , Ʋ ʋ . These, and others, are supported by Unicode , but appear in Latin ranges other than

7260-424: The IPA remained nearly static until the Kiel Convention in 1989, which substantially revamped the alphabet. A smaller revision took place in 1993 with the resurrection of letters for mid central vowels and the retirement of letters for voiceless implosives . The alphabet was last revised in May 2005 with the addition of a letter for a labiodental flap . Apart from the addition and removal of symbols, changes to

7381-532: The IPA.) Of more than 160 IPA symbols, relatively few will be used to transcribe speech in any one language, with various levels of precision. A precise phonetic transcription, in which sounds are specified in detail, is known as a narrow transcription . A coarser transcription with less detail is called a broad transcription. Both are relative terms, and both are generally enclosed in square brackets. Broad phonetic transcriptions may restrict themselves to easily heard details, or only to details that are relevant to

Similarly, implosive [ɗʒ] has been reported from Roglai , but it has also been analyzed as [ʄ] , and the implosive affricates reported from Gitxsan turn out to be lenis ejectives that are sometimes perceived as voiced. Consonants variously called "voiceless implosives," "implosives with glottal closure," or "reverse ejectives" involve

North America is the third-largest continent by area after Asia and Africa . North America's only land connection to South America

8107-429: The United States has been the source of more varieties of dinosaurs than any other modern country. According to paleontologist Peter Dodson, this is primarily due to stratigraphy, climate and geography, human resources, and history. Much of the Mesozoic Era is represented by exposed outcrops in the many arid regions of the continent. The most significant Late Jurassic dinosaur-bearing fossil deposit in North America

9075-458: The conceptual counterparts of spoken sounds, are usually enclosed in slashes (/ /) and tend to use simpler letters with few diacritics. The choice of IPA letters may reflect theoretical claims of how speakers conceptualize sounds as phonemes or they may be merely a convenience for typesetting. Phonemic approximations between slashes do not have absolute sound values. For instance, in English, either

9196-563: The consonant is produced. The main chart includes only consonants with a single place of articulation. Notes Non-pulmonic consonants are sounds whose airflow is not dependent on the lungs. These include clicks (found in the Khoisan languages and some neighboring Bantu languages of Africa), implosives (found in languages such as Sindhi , Hausa , Swahili and Vietnamese ), and ejectives (found in many Amerindian and Caucasian languages ). North America North America

9317-496: The consonant letters ⟨ b ⟩, ⟨ d ⟩, ⟨ f ⟩, ⟨ ɡ ⟩, ⟨ h ⟩, ⟨ k ⟩, ⟨ l ⟩, ⟨ m ⟩, ⟨ n ⟩, ⟨ p ⟩, ⟨ s ⟩, ⟨ t ⟩, ⟨ v ⟩, ⟨ w ⟩, and ⟨ z ⟩ have more or less their word-initial values in English ( g as in gill , h as in hill , though p t k are unaspirated as in spill, still, skill ); and

9438-432: The continent maintains recognized regions as well. In contrast to the common definition of North America, which encompasses the whole North American continent, the term "North America" is sometimes used more narrowly to refer only to four nations, Canada, Greenland, Mexico, and the U.S. The U.S. Census Bureau includes Saint Pierre and Miquelon, but excludes Mexico from its definition. The term Northern America refers to

9559-981: The continent's coasts; principally, the Arctic Archipelago, the Bahamas , Turks and Caicos , the Greater and Lesser Antilles , the Aleutian Islands (some of which are in the Eastern Hemisphere proper), the Alexander Archipelago , the many thousand islands of the British Columbia Coast, and Newfoundland. Greenland , a self-governing Danish island, and the world's largest , is on the same tectonic plate (the North American Plate ) and

9680-599: The continent. The vast majority of North America is on the North American Plate. Parts of western Mexico, including Baja California, and of California , including the cities of San Diego , Los Angeles , and Santa Cruz , lie on the eastern edge of the Pacific Plate , with the two plates meeting along the San Andreas Fault . The southernmost portion of the continent and much of the West Indies lie on

9801-659: The cordillera, while the major islands of Hawaii consist of Neogene volcanics erupted over a hot spot . Central America is geologically active with volcanic eruptions and earthquakes occurring from time to time. In 1976 Guatemala was hit by a major earthquake , killing 23,000 people; Managua, the capital of Nicaragua, was devastated by earthquakes in 1931 and 1972, the last one killing about 5,000 people; three earthquakes devastated El Salvador, one in 1986 and two in 2001; one earthquake devastated northern and central Costa Rica in 2009, killing at least 34 people; in Honduras

9922-748: The cultures of the region commonly reflect Western traditions . However, relatively small parts of North America in Canada, the United States, Mexico, and Central America have indigenous populations that continue adhering to their respective pre-European colonial cultural and linguistic traditions. The Americas were named after the Italian explorer Amerigo Vespucci by German cartographers Martin Waldseemüller and Matthias Ringmann . Vespucci explored South America between 1497 and 1502, and

10043-731: The discussion at hand, and may differ little if at all from phonemic transcriptions, but they make no theoretical claim that all the distinctions transcribed are necessarily meaningful in the language. For example, the English word little may be transcribed broadly as [ˈlɪtəl] , approximately describing many pronunciations. A narrower transcription may focus on individual or dialectical details: [ˈɫɪɾɫ] in General American , [ˈlɪʔo] in Cockney , or [ˈɫɪːɫ] in Southern US English . Phonemic transcriptions, which express

10164-447: The driest in the U.S. Highland climates cut from north to south of the continent, where subtropical or temperate climates occur just below the tropics, as in central Mexico and Guatemala . Tropical climates appear in the island regions and in the subcontinent's bottleneck, found in countries and states bathed by the Caribbean Sea or to the south of the Gulf of Mexico and the Pacific Ocean . Precipitation patterns vary across

10285-470: The end of the Canadian Shield, near the Great Lakes . Climate west of the Cascade Range is described as being temperate weather with average precipitation 20 inches (510 millimeters). Climate in coastal California is described to be Mediterranean , with average temperatures in cities like San Francisco ranging from 57 to 70 °F (14 to 21 °C) over the course of the year. Stretching from

10406-608: The end of words. the alternations /f/  – /v/ in plural formation in one class of nouns, as in knife /naɪf/  – knives /naɪvz/ , which can be represented morphophonemically as {naɪV } – {naɪV+z }. The morphophoneme {V } stands for the phoneme set {/f/, /v/ }. [ˈf\faɪnəlz ˈhɛld ɪn (.) ⸨knock on door⸩ bɑɹsə{ 𝑝 ˈloʊnə and ˈmədɹɪd 𝑝 }] — f-finals held in Barcelona and Madrid. IPA letters have cursive forms designed for use in manuscripts and when taking field notes, but

10527-562: The first American inhabitants sailed from Beringia some 13,000 years ago, with widespread habitation of the Americas during the end of the Last Glacial Period , in what is known as the Late Glacial Maximum , around 12,500 years ago. The oldest petroglyphs in North America date from 15,000 to 10,000 years before present. Genetic research and anthropology indicate additional waves of migration from Asia via

10648-403: The form of a chart. (See History of the IPA .) Not all aspects of the alphabet can be accommodated in a chart of the size published by the IPA. The alveolo-palatal and epiglottal consonants, for example, are not included in the consonant chart for reasons of space rather than of theory (two additional columns would be required, one between the retroflex and palatal columns and the other between

10769-847: The geographic center of either the 50 states, the conterminous United States, or the North American continent." Nonetheless, there is a 4.6-meter (15 ft) field stone obelisk in Rugby claiming to mark the center. The North American continental pole of inaccessibility is located 1,650 km (1,030 mi) from the nearest coastline, between Allen and Kyle, South Dakota at 43°22′N 101°58′W  /  43.36°N 101.97°W  / 43.36; -101.97  ( Pole of Inaccessibility North America ) . Canada can be divided into roughly seven physiographic divisions: The lower 48 U.S. states can be divided into roughly eight physiographic divisions: Mexico can be divided into roughly fifteen physiographic divisions: North America

10890-412: The grapheme ⟨ g ⟩ of Latin script. Some examples of contrasting brackets in the literature: In some English accents, the phoneme /l/ , which is usually spelled as ⟨l⟩ or ⟨ll⟩ , is articulated as two distinct allophones: the clear [l] occurs before vowels and the consonant /j/ , whereas the dark [ɫ] / [lˠ] occurs before consonants, except /j/ , and at

11011-438: The implication of a preferred pronunciation that the IPA might convey. For example, the respelling systems in many American dictionaries (such as Merriam-Webster ) use ⟨y⟩ for IPA [ j] and ⟨sh⟩ for IPA [ ʃ ] , reflecting the usual spelling of those sounds in English. (In IPA, [y] represents the sound of the French ⟨u⟩ , as in tu , and [sh] represents

11132-419: The indigenous people who lived there, including the bison hunters of the Great Plains and the farmers of Mesoamerica . Native groups also are classified by their language families , which included Athapascan and Uto-Aztecan languages. Indigenous peoples with similar languages did not always share the same material culture , however, and were not necessarily always allies. Anthropologists speculate that

11253-468: The land since its creation, but there is no evidence that humans evolved there. The specifics of the initial settlement of the Americas by ancient Asians are subject to ongoing research and discussion. The traditional theory has been that hunters entered the Bering Land Bridge between eastern Siberia and present-day Alaska from 27,000 to 14,000 years ago. A growing viewpoint is that

11374-550: The language. George N. Clements (2002) actually proposes that implosives are phonologically neither obstruents nor sonorants. The vast majority of implosive consonants are voiced , so the glottis is only partially closed. Because the airflow required for voicing reduces the vacuum being created in the mouth, implosives are easiest to make with a large oral cavity. Implosives are most often voiced stops, occasionally voiceless stops. Individual tokens of glottalized sonorants (nasals, trills, laterals, etc.) may also be pronounced with

11495-454: The left to back (glottal) sounds on the right. In official publications by the IPA, two columns are omitted to save space, with the letters listed among "other symbols" even though theoretically they belong in the main chart. They are arranged in rows from full closure (occlusives: stops and nasals) at top, to brief closure (vibrants: trills and taps), to partial closure (fricatives), and finally minimal closure (approximants) at bottom, again with

11616-428: The left to back on the right, and from maximal closure at top to minimal closure at bottom. No vowel letters are omitted from the chart, though in the past some of the mid central vowels were listed among the "other symbols". A pulmonic consonant is a consonant made by obstructing the glottis (the space between the vocal folds) or oral cavity (the mouth) and either simultaneously or subsequently letting out air from

11737-408: The lungs. Pulmonic consonants make up the majority of consonants in the IPA, as well as in human language. All consonants in English fall into this category. The pulmonic consonant table, which includes most consonants, is arranged in rows that designate manner of articulation , meaning how the consonant is produced, and columns that designate place of articulation , meaning where in the vocal tract

11858-657: The mainland in Mexico. With local indigenous allies, the Spanish conquered the Aztec empire in central Mexico in 1521. Spain then established permanent cities in Mexico, Central America, and Spanish South America in the sixteenth century. Once Spaniards conquered the high civilization of the Aztecs and Incas, the Caribbean was a backwater of the Spanish empire. Other European powers began to intrude on areas claimed by Spain, including

11979-927: The middle into the main range of the Rockies and the coast ranges in California , Oregon , Washington , and British Columbia , with the Great Basin—a lower area containing smaller ranges and low-lying deserts—in between. The highest peak is Denali in Alaska. The U.S. Geographical Survey (USGS) states that the geographic center of North America is "6 miles [10 km] west of Balta, Pierce County, North Dakota " at about 48°10′N 100°10′W  /  48.167°N 100.167°W  / 48.167; -100.167 , about 24 kilometers (15 mi) from Rugby, North Dakota . The USGS further states that "No marked or monumented point has been established by any government agency as

12100-454: The name America to North America. In 1538, Gerardus Mercator used the term America on his world map of the entire Western Hemisphere . On his subsequent 1569 map , Mercator called North America "America or New India" ( America sive India Nova ). The Spanish Empire called its territories in North and South America "Las Indias", and the name given to the state body that oversaw the region

12221-565: The next vowel. To take in air sharply in that way is to implode a sound. However, probably more typically, there is no movement of air at all, which contrasts with the burst of the pulmonary plosives. This is the case with many of the Kru languages , for example. That means that implosives are phonetically sonorants (not obstruents) as the concept of sonorant is usually defined. However, implosives can phonologically pattern as both; that is, they may be phonological sonorants or obstruents depending on

12342-493: The northernmost countries and territories of North America: the U.S., Bermuda , Canada, Greenland, and St. Pierre and Miquelon. Although the term does not refer to a unified region, Middle America includes Mexico, Central America, and the Caribbean. North America's largest countries by land area are Canada and the U.S., both of which have well-defined and recognized subregions. In Canada, these include (from east to west) Atlantic Canada , Central Canada , Canadian Prairies ,

12463-440: The northernmost extent of the island named Newfoundland , has provided unmistakable evidence of Norse settlement. Norse explorer Leif Erikson (c. 970–1020 CE) is thought to have visited the area. Erikson was the first European to make landfall on the continent (excluding Greenland). The Mayan culture was still present in southern Mexico and Guatemala when the Spanish conquistadors arrived, but political dominance in

12584-469: The pharyngeal and glottal columns), and the lateral flap would require an additional row for that single consonant, so they are listed instead under the catchall block of "other symbols". The indefinitely large number of tone letters would make a full accounting impractical even on a larger page, and only a few examples are shown, and even the tone diacritics are not complete; the reversed tone letters are not illustrated at all. The procedure for modifying

12705-593: The presence of implosives further forward. One of the few languages with a farther back implosive (specifically the alveolar one [ɗ] ), and without the bilabial implosive, is Yali , a Dani language spoken on the Indonesian side of New Guinea . Implosives are widespread among the languages of Sub-Saharan Africa and Southeast Asia and are found in a few languages of the Amazon Basin . They are rarely reported elsewhere but occur in scattered languages such as

12826-605: The raised but relatively flat plateau of the Canadian Shield in the northeast; and the varied eastern region, which includes the Appalachian Mountains, the coastal plain along the Atlantic seaboard, and the Florida peninsula. Mexico, with its long plateaus and cordilleras , falls largely in the western region, although the eastern coastal plain does extend south along the Gulf. The western mountains are split in

12947-500: The region, and as such rainforest , monsoon , and savanna types can be found, with rains and high temperatures throughout the year. Notable North American fauna include the bison , black bear , jaguar , cougar , prairie dog , turkey , pronghorn , raccoon , coyote , and monarch butterfly . Notable plants that were domesticated in North America include tobacco , maize , squash , tomato , sunflower , blueberry , avocado , cotton , chile pepper , and vanilla . Laurentia

13068-487: The results of the formation of Pangaea was the Appalachian Mountains , which formed some 480 mya, making it among the oldest mountain ranges in the world. When Pangaea began to rift around 200 mya, North America became part of Laurasia , before it separated from Eurasia as its own continent during the mid- Cretaceous period. The Rockies and other western mountain ranges began forming around this time from

13189-427: The same notation as for morphophonology, – exclamation marks, and pipes. For example, ⟨ cot ⟩ would be used for the orthography of the English word cot , as opposed to its pronunciation /ˈkɒt/ . Italics are usual when words are written as themselves (as with cot in the previous sentence) rather than to specifically note their orthography. However, italics are sometimes ambiguous, and italic markup

13310-473: The sequence of consonants in gra ssh opper .) The IPA is also not universal among dictionaries in languages other than English. Monolingual dictionaries of languages with phonemic orthographies generally do not bother with indicating the pronunciation of most words, and tend to use respelling systems for words with unexpected pronunciations. Dictionaries produced in Israel use the IPA rarely and sometimes use

13431-467: The sound of the English digraph ⟨ch⟩ may be transcribed in IPA with a single letter: [c] , or with multiple letters plus diacritics: [t̠̺͡ʃʰ] , depending on how precise one wishes to be. Slashes are used to signal phonemic transcription ; therefore, /tʃ/ is more abstract than either [t̠̺͡ʃʰ] or [c] and might refer to either, depending on the context and language. Occasionally, letters or diacritics are added, removed, or modified by

13552-509: The vowel letters ⟨ a ⟩, ⟨ e ⟩, ⟨ i ⟩, ⟨ o ⟩, ⟨ u ⟩ correspond to the (long) sound values of Latin: [i] is like the vowel in mach i ne , [u] is as in r u le , etc. Other Latin letters, particularly ⟨ j ⟩, ⟨ r ⟩ and ⟨ y ⟩, differ from English, but have their IPA values in Latin or other European languages. This basic Latin inventory

13673-463: The vowel of pick or the vowel of peak may be transcribed as /i/ , so that pick , peak would be transcribed as /ˈpik, ˈpiːk/ or as /ˈpɪk, ˈpik/ ; and neither is identical to the vowel of the French pique , which would also be transcribed /pik/ . By contrast, a narrow phonetic transcription of pick , peak , pique could be: [pʰɪk] , [pʰiːk] , [pikʲ] . IPA is popular for transcription by linguists. Some American linguists, however, use

13794-438: The world's languages, the occurrence of implosives shows a strong cline from front to back points of articulation. Bilabial [ɓ] is the most common implosive. It is very rarely lacking in the inventory of languages which have implosive stops. On the other hand, implosives with a back articulation (such as velar [ɠ] ) occur much less frequently; apart from a few exceptions, the presence of the velar implosive [ɠ] goes along with

13915-612: Was based on the Romic alphabet , an English spelling reform created by Henry Sweet that in turn was based on the Palaeotype alphabet of Alexander John Ellis , but to make it usable for other languages the values of the symbols were allowed to vary from language to language. For example, the sound [ ʃ ] (the sh in shoe ) was originally represented with the letter ⟨c⟩ for English but with ⟨x⟩ for French and German; with German, ⟨c⟩

14036-549: Was called the Council of the Indies . The United Nations and its statistics division recognize North America as including three regions: Northern America, Central America , and the Caribbean . "Northern America" is a distinct term from "North America", excluding Central America, which itself may or may not include Mexico . In the limited context of regional trade agreements, the term is used to reference three nations: Canada,

14157-561: Was estimated as over 592 million people in 23 independent states , or about 7.5% of the world's population. In human geography , the terms "North America" and "North American" can refer to Canada, the United States, Mexico, and Greenland or, alternatively, Canada, Greenland and the US (Mexico being classified as part of Latin America ) or simply Canada and the US (Greenland being classified as either Arctic or European (due to its political status as

14278-446: Was extended by adding small-capital and cursive forms, diacritics and rotation. The sound values of these letters are related to those of the original letters, and their derivation may be iconic. For example, letters with a rightward-facing hook at the bottom represent retroflex equivalents of the source letters, and small capital letters usually represent uvular equivalents of their source letters. There are also several letters from

14399-817: Was in Jamestown, Virginia in 1607, followed by additional colonial establishments on the east coast from present-day Georgia in the south to Massachusetts in the north, forming the Thirteen Colonies of British America. The English did not establish settlements north or east of the St. Lawrence Valley in present-day Canada until after the conclusion of the American Revolutionary War . Britain's early settlements in present-day Canada included St. John's, Newfoundland in 1630 and Halifax, Nova Scotia in 1749. The first permanent French settlement

14520-473: Was the first European to suggest that the Americas represented a landmass not then known to the Europeans. In 1507, Waldseemüller published a world map, and placed the word "America" on the continent of present-day South America. The continent north of present-day Mexico was then referred to as Parias. On a 1553 world map published by Petrus Apianus , North America was called "Baccalearum", meaning "realm of

14641-402: Was used for the [ x ] sound of Bach . With a growing number of transcribed languages this proved impractical, and in 1888 the values of the letters were made uniform across languages. This would provide the base for all future revisions. Since its creation, the IPA has undergone a number of revisions. After relatively frequent revisions and expansions from the 1890s to the 1940s,
