The Scotia Arc is the island arc system forming the north, east and south border of the Scotia Sea . The northern border, the North Scotia Ridge, comprises (from west to east): Isla de los Estados at the tip of Tierra del Fuego , the Burdwood , Davis, and Aurora Banks; the Shag , South Georgia Island and Clerke Rocks . The eastern border comprises the volcanic South Sandwich Islands flanked by the South Sandwich Trench . The southern border, the South Scotia Ridge, comprises (east to west): Herdman , Discovery , Bruce , Pirie , and Jane Banks ; the South Orkney Islands and Elephant Island . Finally, the Bransfield Strait separates the arc from the South Shetland Islands and James Ross Island flanking the tip of the Antarctic Peninsula .

88-557: The Scotia Arc surrounds the small Scotia and South Sandwich Plates . The arc is formed by continental fragments that once formed a land bridge between South America and Antarctica, which was once part of the subduction margin that still forms the Andes . An ancestral arc, which formed a separate subduction system, broke through this land bridge and started to form the Scotia Sea by eastward back-arc extension driven by subduction of

176-603: A considerable number of words from Arabic , as well as a minor influence from the Germanic Gothic language through the period of Visigoth rule in Iberia. In addition, many more words were borrowed from Latin through the influence of written language and the liturgical language of the Church. The loanwords were taken from both Classical Latin and Renaissance Latin , the form of Latin in use at that time. According to

264-522: A dramatic change in the pronunciation of its sibilant consonants , known in Spanish as the reajuste de las sibilantes , which resulted in the distinctive velar [x] pronunciation of the letter ⟨j⟩ and—in a large part of Spain—the characteristic interdental [θ] ("th-sound") for the letter ⟨z⟩ (and for ⟨c⟩ before ⟨e⟩ or ⟨i⟩ ). See History of Spanish (Modern development of

352-482: A first language by Spaniards and educated Filipinos ( Ilustrados ). Despite a public education system set up by the colonial government, by the end of Spanish rule in 1898, only about 10% of the population had knowledge of Spanish, mostly those of Spanish descent or elite standing. Spanish continued to be official and used in Philippine literature and press during the early years of American administration after

440-478: A long history in the territory of the current-day United States dating back to the 16th century. In the wake of the 1848 Guadalupe Hidalgo Treaty , hundreds of thousands of Spanish speakers became a minoritized community in the United States. The 20th century saw further massive growth of Spanish speakers in areas where they had been hitherto scarce. According to the 2020 census, over 60 million people of

528-508: A primarily Hassaniya Arabic -speaking territory, Spanish was officially spoken as the language of the colonial administration during the late 19th and 20th centuries. Today, Spanish is present in the partially-recognized Sahrawi Arab Democratic Republic as its secondary official language, and in the Sahrawi refugee camps in Tindouf ( Algeria ), where the Spanish language is still taught as

616-617: A second language features characteristics involving the variability of the vowel system. While far from its heyday during the Spanish protectorate in Morocco , the Spanish language has some presence in northern Morocco , stemming for example from the availability of certain Spanish-language media. According to a 2012 survey by Morocco's Royal Institute for Strategic Studies (IRES), penetration of Spanish in Morocco reaches 4.6% of

704-531: A second language, largely by Cuban educators. The number of Spanish speakers is unknown. Spanish is also an official language of the African Union . Spanish was an official language of the Philippines from the beginning of Spanish administration in 1565 to a constitutional change in 1973. During Spanish colonization , it was the language of government, trade, and education, and was spoken as

792-743: A series of geological transformations during the Cretaceous , through which South Georgia was first buried, then made a topographic feature again by the Late Cretaceous. At about 45 Ma, South Georgia, still part of the South American plate , got buried again and something, possibly rotation of the Fuegian Andes, completed the break-up and allowed South Georgia a second exhumation . During the Oligocene (34–23 Ma) South Georgia

880-710: A small and heavily dissected bank degenerates into several outcrops dominated by Paleozoic and Cretaceous rocks. A small basin, Powel Basin, separates this cluster from the South Orkney microcontinent composed of Triassic and younger rocks. The eastern continuation of the ridge, the Scotia Arc east of the South Sandwich plate , are the South Sandwich island arc and trench . This volcanic active island arc has submerged ancestors in Jane and Discovery banks in

968-416: Is cognate to the root word of satisfacer ("to satisfy"), and hecho ("made") is similarly cognate to the root word of satisfecho ("satisfied"). Compare the examples in the following table: Some consonant clusters of Latin also produced characteristically different results in these languages, as shown in the examples in the following table: In the 15th and 16th centuries, Spanish underwent

1056-601: Is a back-arc spreading ridge that formed due to subduction of the South American plate below the South Sandwich plate along the South Sandwich Island arc. Exact spreading rates are still being disputed in the literature, but it has been agreed that rates range between 60 and 90 mm/yr. The banks of northern Central Scotia Sea are superposed on oceanic basement and the spreading centre of

1144-694: Is a minor plate whose movement is largely controlled by the two major plates that surround it: the Antarctic plate and the South American plate . The Scotia plate takes its name from the steam yacht Scotia of the Scottish National Antarctic Expedition (1902–04), the expedition that made the first bathymetric study of the region. Roughly rhomboid, extending between 50°S 70°W  /  50°S 70°W  / -50; -70 and 63°S 20°W  /  63°S 20°W  / -63; -20 ,

1232-454: Is estimated that about 486 million people speak Spanish as a native language , making it the second most spoken language by number of native speakers . An additional 75 million speak Spanish as a second or foreign language , making it the fourth most spoken language in the world overall after English, Mandarin Chinese, and Hindi with a total number of 538 million speakers. Spanish is also

1320-761: Is heavily influenced by Venezuelan Spanish. In addition to sharing most of its borders with Spanish-speaking countries, the creation of Mercosur in the early 1990s induced a favorable situation for the promotion of Spanish language teaching in Brazil . In 2005, the National Congress of Brazil approved a bill, signed into law by the President , making it mandatory for schools to offer Spanish as an alternative foreign language course in both public and private secondary schools in Brazil. In September 2016 this law

1408-563: Is made of oceanic crust and continental fragments now distributed around the Scotia Sea . Before the formation of the plate began 40  million years ago (40Ma), these fragments formed a continuous landmass from Patagonia to the Antarctic Peninsula along an active subduction margin. At present, the plate is almost completely submerged, with only the small exceptions of South Georgia on its northeastern edge and

1496-415: Is passing through Tierra del Fuego . The northern ridge stretches from Isla de los Estados off Tierra del Fuego in the west to the microcontinent South Georgia in the east, with a series of shallow banks in between: Burdwood , Davis, Barker, and Shag Rocks . North of the ridge is the 3 km (1.9 mi) deep Falkland Trough . Experts in plate tectonics have been unable to determine whether

1584-732: Is related to Castile ( Castilla or archaically Castiella ), the kingdom where the language was originally spoken. The name Castile , in turn, is usually assumed to be derived from castillo ('castle'). In the Middle Ages , the language spoken in Castile was generically referred to as Romance and later also as Lengua vulgar . Later in the period, it gained geographical specification as Romance castellano ( romanz castellano , romanz de Castiella ), lenguaje de Castiella , and ultimately simply as castellano (noun). Different etymologies have been suggested for

1672-844: Is spoken by very small communities in Angola due to Cuban influence from the Cold War and in South Sudan among South Sudanese natives that relocated to Cuba during the Sudanese wars and returned for their country's independence. Spanish is also spoken in the integral territories of Spain in Africa, namely the cities of Ceuta and Melilla and the Canary Islands , located in the Atlantic Ocean some 100 km (62 mi) off

1760-813: Is the de facto national language of the country, Spanish is often used in public services and notices at the federal and state levels. Spanish is also used in administration in the state of New Mexico . The language has a strong influence in major metropolitan areas such as those of Los Angeles , Miami , San Antonio , New York , San Francisco , Dallas , Tucson and Phoenix of the Arizona Sun Corridor , as well as more recently, Chicago , Las Vegas , Boston , Denver , Houston , Indianapolis , Philadelphia , Cleveland , Salt Lake City , Atlanta , Nashville , Orlando , Tampa , Raleigh and Baltimore-Washington, D.C. due to 20th- and 21st-century immigration. Although Spanish has no official recognition in

1848-729: The Early Eocene (55 Ma) saw rift basin formation in the Fuegan Andes which led to crustal extension: the first sign of separation between the two continents and the formation of the South Scotia Sea and South Scotia Ridge. Spreading in the West Scotia Sea led to the further lengthening of the North Scotia Ridge and South Georgia moving further east. Spreading in the West Scotia Sea also finally led to

1936-607: The Iberian Peninsula of Europe . Today, it is a global language with about 500 million native speakers, mainly in the Americas and Spain , and about 600 million when including second language speakers. Spanish is the official language of 20 countries , as well as one of the six official languages of the United Nations . Spanish is the world's second-most spoken native language after Mandarin Chinese ;

2024-631: The Mid-Atlantic Ridge grew from 1200 km to 7000 km. This led to compressional deformations along the western margin of the South American plate and the obduction of the Rocas Verdes basement onto this margin. Structures associated with this obduction are found from Tierra del Fuego to South Georgia. The acceleration of the westward motion of South America and the inversion of the Rocas Verde Basin finally lead to

2112-872: The South American Plate (also located east of the Scotia Arc). Today, the Scotia Arc forms a discontinuous link between South America and Antarctica. It is considered a continuation of the Andes, and the antarctic part of that mountain range is called the Antarctandes . The Scotia Arc is also an important barrier between the Pacific and Atlantic Oceans, and therefore for the Antarctic Circumpolar Current . The formation of

Spanish has historically had a significant presence on the Dutch Caribbean islands of Aruba , Bonaire and Curaçao ( ABC Islands ) throughout the centuries and in present times. The majority of the populations of each island (especially Aruba) speaking Spanish at varying although often high degrees of fluency. The local language Papiamentu (Papiamento on Aruba)

Nevertheless, despite a significant decrease in influence and speakers, Spanish remained an official language of the Philippines upon independence in 1946, alongside English and Filipino , a standardized version of Tagalog . Spanish was briefly removed from official status in 1973 but reimplemented under

2376-608: The collapse of the Western Roman Empire in the 5th century. The oldest Latin texts with traces of Spanish come from mid-northern Iberia in the 9th century, and the first systematic written use of the language happened in Toledo , a prominent city of the Kingdom of Castile , in the 13th century. Spanish colonialism in the early modern period spurred the introduction of the language to overseas locations, most notably to

2464-404: The 2021–2022 school year alone. The local business process outsourcing industry has also helped boost the language's economic prospects. Today, while the actual number of proficient Spanish speakers is around 400,000, or under 0.5% of the population, a new generation of Spanish speakers in the Philippines has likewise emerged, though speaker estimates vary widely. Aside from standard Spanish,

2552-595: The 20th century, Spanish was introduced to Equatorial Guinea and the Western Sahara , and to areas of the United States that had not been part of the Spanish Empire, such as Spanish Harlem in New York City . For details on borrowed words and other external influences upon Spanish, see Influences on the Spanish language . Spanish is the primary language in 20 countries worldwide. As of 2023, it

2640-465: The Americas. As a Romance language, Spanish is a descendant of Latin. Around 75% of modern Spanish vocabulary is Latin in origin, including Latin borrowings from Ancient Greek. Alongside English and French , it is also one of the most taught foreign languages throughout the world. Spanish is well represented in the humanities and social sciences . Spanish is also the third most used language on

2728-844: The Burdwood Bank on the western North Scotia Ridge south of the Falkland Islands. The Rocas Verdes basin was filled with turbidites derived from the volcanic arc on its Pacific margin and partly from its continental margin. The Weddell Sea continued to expand which led to the extension between the Patagonian Andes and the Antarctic Peninsula. In the Mid-Cretaceous (100 Ma) the spreading rate in South Atlantic increased significantly and

2816-629: The Caribbean plate, and both plates also had a major impact on global climate when they closed the two major gateways between the Pacific and Atlantic Oceans during the Mesozoic and Cenozoic . The northern edge of the Scotia plate is bounded by the South American plate, forming the North Scotia Ridge. The North Scotia ridge is a left-lateral, or sinistral, transform boundary with a transform rate of roughly 7.1 mm/yr. The Magallanes–Fagnano Fault

2904-689: The Early Oligocene (90–30 Ma) little changed in the region, except for the subduction of the Phoenix plate along the Shackleton Fracture Zone. The Late Paleocene and Early Eocene (60–50 Ma) saw the formation of South Scotia Sea and South Scotia Ridge — the first sign of separation of the southern Andes and the Antarctic Peninsula ;— which resulted in seafloor spreading in the West Scotia Sea and hence

2992-703: The East Scotia Ridge. South Georgia's eastward migration ended about 9 Ma when the microcontinent collided with the Northeast Georgia Rise large igneous province on the South American Plate, north-east of South Georgia. A submerged equivalent to the current South Sandwich Arc was relocated westward by the same spreading centre. After, and probably because of, the collision, the East Scotia Sea spreading centre split

3080-654: The Equatoguinean education system and is the primary language used in government and business. Whereas it is not the mother tongue of virtually any of its speakers, the vast majority of the population is proficient in Spanish. The Instituto Cervantes estimates that 87.7% of the population is fluent in Spanish. The proportion of proficient Spanish speakers in Equatorial Guinea exceeds the proportion of proficient speakers in other West and Central African nations of their respective colonial languages. Spanish

3168-705: The Iberian Peninsula. These languages included Proto-Basque , Iberian , Lusitanian , Celtiberian and Gallaecian . The first documents to show traces of what is today regarded as the precursor of modern Spanish are from the 9th century. Throughout the Middle Ages and into the modern era , the most important influences on the Spanish lexicon came from neighboring Romance languages — Mozarabic ( Andalusi Romance ), Navarro-Aragonese , Leonese , Catalan/Valencian , Portuguese , Galician , Occitan , and later, French and Italian . Spanish also borrowed

3256-647: The Late Cretaceous South America started to move west relative to Antarctica. Little changed in the region between the Late Cretaceous and Oligocene (90-30 Ma) except for the subduction of the Phoenix Plate on the Pacific margin of the land bridge that still connected South America and Antarctica — what would become the Drake Passage was at this time a cusp on the Pacific side of the land bridge. The Late Paleocene to

The Gramática de la lengua castellana , written in Salamanca in 1492 by Elio Antonio de Nebrija , was the first grammar written for a modern European language. According to a popular anecdote, when Nebrija presented it to Queen Isabella I , she asked him what was the use of such a work, and he answered that language is the instrument of empire. In his introduction to

Thought to have formed during the early Eocene with the opening of the Drake Passage that separates Antarctica and South America, it

3520-413: The Scotia Arc was initiated by an acceleration in South America's westward migration in the mid- Cretaceous ( 120 to 83 million years ago , Ma) which led to the uplift of the Fuegan Andes and the then adjacent and embryonic North Scotia Ridge. The uplift of the ridge initiated the eastward migration of the South Georgia microcontinent from Tierra del Fuego towards its current location. In

3608-473: The Scotia plate can be dated to 26–5.5 Ma suggesting spreading was active before spreading completely translated to the East Scotia Ridge at about 6 Ma. It was assumed that spreading cessation occurred where the W7 segment joins the North Scotia Ridge. However basalt lava sampled from the eastern side of the W7 segment were found to be between 93 and 137 million years old and the geochemistry of arc-like basalts suggests no sea floor spreading actually occurred in

3696-403: The South Georgian Islands are part of the Scotia plate or have been recently accreted to the South American plate. Surface expressions of the plate boundary are found north of the islands suggesting a long-term presence of the transform fault there. Yet seismic studies have identified strain and thrusting south of the islands indicating the possible shift of the transform fault to an area south of

3784-437: The South Shetland Islands of Antarctica was a small opening with limited circulation. A change in relative motion between the South American plate and the Antarctic plate would have severe effects, causing seafloor spreading and the formation of the Scotia plate. Marine geophysical data indicates that motion between the South American plate and the Antarctic plate shifted from N–S to WNW–ESE accompanied by an eightfold increase in

3872-424: The Spanish-speaking world, Spanish is called not only español but also castellano (Castilian), the language from the Kingdom of Castile , contrasting it with other languages spoken in Spain such as Galician , Basque , Asturian , Catalan/Valencian , Aragonese , Occitan and other minor languages. The Spanish Constitution of 1978 uses the term castellano to define the official language of

3960-502: The U.S. population were of Hispanic or Hispanic American by origin. In turn, 41.8 million people in the United States aged five or older speak Spanish at home, or about 13% of the population. Spanish predominates in the unincorporated territory of Puerto Rico , where it is also an official language along with English. Spanish is by far the most common second language in the country, with over 50 million total speakers if non-native or second-language speakers are included. While English

4048-519: The W7 segment itself. This has resulted in the suggestion that the W7 segment is a downfaulted block of the North Scotia Ridge of the Fuegian Andes continental margin arc, or is potentially related to the putative Cretaceous Central Scotia Sea. The timing of the formation of the Scotia plate and opening of the Drake Passage have long been the subject of much debate due to the important implications for changes in ocean currents and shifts in paleoclimate . The thermal isolation of Antarctica , engendering

4136-457: The West Scotia Sea. Analyses of samples of volcaniclastic rocks from these sites indicate they are constructs of a continental arc and in some cases oceanic arc similar to those being formed in the currently active South Sandwich Arc. The oldest volcanic arc activity in the central and eastern regions of the Scotia Sea are 28.5 Ma. The South Sandwich forarc originated in the Central Scotia Sea at that time but has since been translated eastward by

4312-415: The ancestral South Sandwich Arc leaving a remnant arc under the Central Scotia Sea. The collision also produced the rugged Allardyce Range on South Georgia, making the 3,000 m (9,800 ft)-high range three times higher than the conjugate rocks on Navarino Island in Tierra del Fuego. The driving mechanism behind the formation of the arc, as proposed by Alvarez 1982 , is a mantle return-flow from

4400-450: The back-arc spreading centre of the East Scotia Ridge. One of the most prominent features in the Scotia plate itself is the median valley known as the West Scotia Ridge. It was produced by two plates that are no longer independently active: the Magallanes and Central Scotia plates so is an extinct spreading center. The ridge consists of seven segments separated by right-lateral transform faults of various lengths. The western region of

4488-566: The classic hispanus or hispanicus took the suffix -one from Vulgar Latin , as happened with other words such as bretón (Breton) or sajón (Saxon). Like the other Romance languages , the Spanish language evolved from Vulgar Latin , which was brought to the Iberian Peninsula by the Romans during the Second Punic War , beginning in 210 BC. Several pre-Roman languages (also called Paleohispanic languages )—some distantly related to Latin as Indo-European languages , and some that are not related at all—were previously spoken in

4576-446: The consonant written b (a bilabial with plosive and fricative allophones). In modern Spanish, there is no difference between the pronunciation of orthographic b and v . Typical of Spanish (as also of neighboring Gascon extending as far north as the Gironde estuary , and found in a small area of Calabria ), attributed by some scholars to a Basque substratum was the mutation of Latin initial f into h- whenever it

4664-404: The country's constitution. In recent years changing attitudes among non-Spanish speaking Filipinos have helped spur a revival of the language, and starting in 2009 Spanish was reintroduced as part of the basic education curriculum in a number of public high schools, becoming the largest foreign language program offered by the public school system, with over 7,000 students studying the language in

In early Spanish (but not in Catalan or Portuguese) it merged with

4928-404: The formation of the Antarctic ice sheet , has largely been attributed to the opening of the Drake Passage. The Scotia plate originated about 80  million years ago (Ma), during the late Mesozoic at the Panthalassic margins of the Gondwana supercontinent between two Precambrian cratons, the Kalahari and East Antarctic Cratons , now located in Africa and Antarctica. Its development

Due to its proximity to Spanish-speaking countries and small existing native Spanish speaking minority, Trinidad and Tobago has implemented Spanish language teaching into its education system. The Trinidadian and Tobagonian government launched

5104-454: The grammar, dated 18 August 1492, Nebrija wrote that "... language was always the companion of empire." From the 16th century onwards, the language was taken to the Spanish-discovered America and the Spanish East Indies via Spanish colonization of America . Miguel de Cervantes , author of Don Quixote , is such a well-known reference in the world that Spanish is often called la lengua de Cervantes ("the language of Cervantes"). In

The banks of the North Scotia Ridge contain volcanic rocks similar to those found in Tierra del Fuego, including on Isla de los Estados on the easternmost tip. During the early Eocene (50 Ma), the Drake Passage between the southern tip of South America at Cape Horn and

It has also been suggested that the plate bearing the islands may have broken off from the Scotia plate, forming a new independent South Georgia microplate, yet there is little evidence to make this conclusion. The South Georgia microcontinent was originally connected to the Roca Verdes back-arc basin (southernmost Tierra del Fuego ) until the Eocene . Before that, this basin went through

5544-423: The language's hegemony in an intensely centralising Spanish state were established from the 18th century onward. Other European territories in which it is also widely spoken include Gibraltar and Andorra . Spanish is also spoken by immigrant communities in other European countries, such as the United Kingdom , France , Italy , and Germany . Spanish is an official language of the European Union . Today,

The Spanish spoken in the Canary Islands traces its origins back to the Castilian conquest in the 15th century , and, in addition to a resemblance to Western Andalusian speech patterns, it also features strong influence from the Spanish varieties spoken in the Americas, which in turn have also been influenced historically by Canarian Spanish. The Spanish spoken in North Africa by native bilingual speakers of Arabic or Berber who also speak Spanish as

It is moving WSW at 2.2 cm (0.87 in)/year and the South Sandwich plate is moving east at 5.5 cm (2.2 in)/year in an absolute reference frame. Its boundaries are defined by the East Scotia Ridge, the North Scotia Ridge, the South Scotia Ridge, and the Shackleton Fracture Zone . The Scotia plate

5984-465: The plate is bounded by the Shetland microplate separating the Shackleton Fracture Zone and the South Scotia Ridge. North of South Shetland Islands and along the southern half of the Shackleton Fracture Zone is the remnant of the Phoenix plate (also known as Drake or Aluk Plate). Around 47 Ma the subduction of the Phoenix plate started as the propagation of the Pacific-Antarctic Ridge continued. The last collision between Phoenix ridge segments and

6072-481: The population. Many northern Moroccans have rudimentary knowledge of Spanish, with Spanish being particularly significant in areas adjacent to Ceuta and Melilla. Spanish also has a presence in the education system of the country (through either selected education centers implementing Spain's education system, primarily located in the North, or the availability of Spanish as foreign language subject in secondary education). In Western Sahara , formerly Spanish Sahara ,

6160-417: The rifting of the South Orkney microcontinent from the tip of the Antarctic Peninsula. This event initiated the South Scotia Ridge. The banks of the South Scotia Ridge are made of continental crust that rifted off the land bridge 40-30 Ma. The banks on the northern Central Scotia Sea, on the other hand, are volcanic constructs overlaying an oceanic basement . Parts of this basement form the spreading centre of

6248-424: The separation between South America and Antarctica. Seafloor spreading in the West Scotia Sea continued until 6.6-5.9 Ma. The oldest volcanic activity in the Central and Eastern Scotia Sea, i.e. the first signs of a volcanic arc, has been dated to 28.5 Ma. The South Sandwich Islands fore-arc originated in the Central Scotia Sea and was translated eastward by the back-arc spreading centre in the East Scotia Sea, i.e.

6336-538: The separation rate. This shift in spreading initiated crustal thinning and by 30–34 Ma, the West Scotia Ridge formed. A complex pattern of spreading prior to 26 Ma is probably present in the oldest parts of this spreading regime; i.e. west of Terror Rise (north of Elephant Island ) and on the shelf slope of Tierra del Fuego. Until 17 Ma the Central Scotia plate moved quickly eastwards, fuelled by

6424-617: The southern half of the Antarctic-Scotia plate boundary. The relative motion between the Scotia plate and the Antarctic plate on the western boundary is 7.5–8.7 mm/yr. Though the South Scotia Ridge is overall a transform fault, small sections of the ridge are spreading to make up for the somewhat jagged shape of the boundary. At the eastern tip of the Antarctic Peninsula , the beginning of South Scotia Ridge,

Fragments of the inverted oceanic basement of this basin are preserved as ophiolitic complexes in this area, including the Larsen Harbour complex on South Georgia. This makes it possible to restore the original position of the South Georgia microcontinent south of

6600-464: The southern ridge. The western edge of the plate is bounded by the Antarctic plate, forming the Shackleton Fracture Zone and the southern Chile Trench . The Southern Chile Trench is a southern extension of the subduction of the Antarctic and Nazca plates below South America. Heading south along the ridge, the subduction rate decreases until its remaining oblique motion evolves into the Shackleton Fracture Zone transform boundary. The south-western edge of

6688-744: The southern tip of South America. Together with the South Sandwich Plate , the Scotia plate joins the southernmost Andes to the Antarctic Peninsula, just like the Caribbean plate joins the northernmost Andes to North America, and these two plates are comparable in several ways. Both have volcanic arcs at their eastern ends, the South Sandwich Islands on the Sandwich Plate and the Lesser Antilles on

6776-406: The subduction zone was 6.5 Ma and at 3.3 Ma movements had stopped and the remnants of the Phoenix plate was incorporated into the Antarctic plate. The southern part of the Shackleton Fracture Zone is the former eastern edge of the Phoenix plate. The eastern edge of the Scotia plate is a spreading ridge bounded by the South Sandwich microplate , forming the East Scotia Ridge. The East Scotia Ridge

6864-670: The term español (Spanish). According to the Royal Spanish Academy, español derives from the Occitan word espaignol and that, in turn, derives from the Vulgar Latin * hispaniolus ('of Hispania'). Hispania was the Roman name for the entire Iberian Peninsula . There are other hypotheses apart from the one suggested by the Royal Spanish Academy. Spanish philologist Ramón Menéndez Pidal suggested that

6952-444: The theories of Ramón Menéndez Pidal , local sociolects of Vulgar Latin evolved into Spanish, in the north of Iberia, in an area centered in the city of Burgos , and this dialect was later brought to the city of Toledo , where the written standard of Spanish was first developed, in the 13th century. In this formative stage, Spanish developed a strongly differing variant from its close cousin, Leonese , and, according to some authors,

7040-640: The third most used language on the Internet , after English and Chinese. Spanish is the official language of Spain . Upon the emergence of the Castilian Crown as the dominant power in the Iberian Peninsula by the end of the Middle Ages, the Romance vernacular associated with this polity became increasingly used in instances of prestige and influence, and the distinction between "Castilian" and "Spanish" started to become blurred. Hard policies imposing

7128-585: The whole of Spain, in contrast to las demás lenguas españolas (lit. "the other Spanish languages "). Article III reads as follows: El castellano es la lengua española oficial del Estado. ... Las demás lenguas españolas serán también oficiales en las respectivas Comunidades Autónomas... Castilian is the official Spanish language of the State. ... The other Spanish languages shall also be official in their respective Autonomous Communities... The Royal Spanish Academy ( Real Academia Española ), on

7216-506: The world's fourth-most spoken language overall after English , Mandarin Chinese, and Hindustani ( Hindi - Urdu ); and the world's most widely spoken Romance language. The country with the largest population of native speakers is Mexico . Spanish is part of the Ibero-Romance language group , in which the language is also known as Castilian ( castellano ). The group evolved from several dialects of Vulgar Latin in Iberia after

7304-723: Was also influenced by the Río de la Plata Craton in South America. The initial cause for its formation was the break-up of Gondwana in what became the south-west Indian Ocean. The earliest marine fossils found on the Maurice Ewing Bank , on the eastern end of the Falkland Plateau , are associated with the Indian and Tethys Oceans and probably slightly more than 150 Ma. The Weddell Sea opened and spread along

7392-689: Was developed in the cities of Toledo , in the 13th to 16th centuries, and Madrid , from the 1570s. The development of the Spanish sound system from that of Vulgar Latin exhibits most of the changes that are typical of Western Romance languages , including lenition of intervocalic consonants (thus Latin vīta > Spanish vida ). The diphthongization of Latin stressed short e and o —which occurred in open syllables in French and Italian, but not at all in Catalan or Portuguese—is found in both open and closed syllables in Spanish, as shown in

7480-622: Was distinguished by a heavy Basque influence (see Iberian Romance languages ). This distinctive dialect spread to southern Spain with the advance of the Reconquista , and meanwhile gathered a sizable lexical influence from the Arabic of Al-Andalus , much of it indirectly, through the Romance Mozarabic dialects (some 4,000 Arabic -derived words, make up around 8% of the language today). The written standard for this new language

7568-713: Was followed by a vowel that did not diphthongize. The h- , still preserved in spelling, is now silent in most varieties of the language, although in some Andalusian and Caribbean dialects, it is still aspirated in some words. Because of borrowings from Latin and neighboring Romance languages, there are many f -/ h - doublets in modern Spanish: Fernando and Hernando (both Spanish for "Ferdinand"), ferrero and herrero (both Spanish for "smith"), fierro and hierro (both Spanish for "iron"), and fondo and hondo (both words pertaining to depth in Spanish, though fondo means "bottom", while hondo means "deep"); additionally, hacer ("to make")

7656-402: Was reburied again as seafloor spreading took place in the West Scotia Sea. 10 Ma, finally, the South Georgia microcontinent was uplifted as a result of the collision with the Northeast Georgia Rise . The southern edge of the plate is bordered by the Antarctic plate, forming the South Scotia Ridge, a left-lateral transform boundary sliding at a rate of roughly 7.4–9.5 mm/yr that occupies

7744-462: Was revoked by Michel Temer after the impeachment of Dilma Rousseff . In many border towns and villages along Paraguay and Uruguay, a mixed language known as Portuñol is spoken. Equatorial Guinea is the only Spanish-speaking country located entirely in Africa, with the language introduced during the Spanish colonial period . Enshrined in the constitution as an official language (alongside French and Portuguese), Spanish features prominently in
