54-550: From source to mouth the Paranapanema River has an elevation drop of 677 metres (2,221 ft). The river's length is about 929 kilometres (577 mi). It flows generally west, reaching the Paraná River at an altitude of about 233 metres (764 ft). The sources of the river are protected by the 22,269 hectares (55,030 acres) Nascentes do Paranapanema State Park , created in 2012. The sources are situated in

108-427: A joint project between Paraguay and Argentina. The massive reservoir formed by the project has been the source of a number of problems for people living along the river, most notably the poorer merchants and residents in the low-lying areas of Encarnación, a major city on the southern border of Paraguay. River levels rose dramatically upon completion of the dam, flooding out large sections of the city's lower areas. From

162-429: A language "so copious and elegant that it can compete with the most famous [of languages]". The name "Guarani" is generally used for the official language of Paraguay. However, this is part of a dialect chain , most of whose components are also often called Guarani. While Guarani, in its Classical form , was the only language spoken in the expansive missionary territories, Paraguayan Guarani has its roots outside of

216-487: A nasal vowel, and if the consonant is voiced, it takes its nasal allophone. If a stressed syllable is nasal, the nasality spreads in both directions until it bumps up against a stressed syllable that is oral. This includes affixes , postpositions , and compounding. Voiceless consonants do not have nasal allophones, but they do not interrupt the spread of nasality. For example, However, a second stressed syllable, with an oral vowel, will not become nasalized: That is, for

270-481: A predicative possessive reading. Furthermore, the conjugations vary slightly according to the stem being oral or nasal. Negation is indicated by a circumfix n(d)(V)-...-(r)i in Guarani. The preverbal portion of the circumfix is nd- for oral bases and n- for nasal bases. For 2nd person singular, an epenthetic -e- is inserted before the base, for 1st person plural inclusive, an epenthetic -a-

324-619: A series of seven cascades. This natural feature was said to rival the world-famous Iguazu Falls to the south. The falls were flooded, however, by the construction of the Itaipu Dam , which began operating in 1984. For approximately the next 200 km (120 mi), the Paraná flows southward and forms a natural boundary between Paraguay and Brazil until the confluence with the Iguazu River . Further upstream from this confluence, however,

378-450: A vowel. The glottal stop , called puso in Guarani, is only written between vowels, but occurs phonetically before vowel-initial words. Because of this, some words have several glottal stops near each other that consequently undergo a number of different dissimilation techniques. For example, "I drink water" ʼaʼyʼu is pronounced hayʼu . This suggests that irregularity in verb forms derives from regular sound change processes in

432-506: A word with a single stressed vowel, all voiced segments will be either oral or nasal, while voiceless consonants are unaffected, as in oral /ᵐbotɨ/ vs nasal /mõtɨ̃/ . Guarani is a highly agglutinative language , often classified as polysynthetic . It is a fluid-S type active language , and it has been classified as a 6th class language in Milewski's typology . It uses subject–verb–object (SVO) word order usually, but object–verb when

486-453: A written language relatively recently. Its modern alphabet is a subset of the Latin script (with "J", "K" and "Y" but not "W"), complemented with two diacritics and six digraphs . Its orthography is largely phonemic , with letter values mostly similar to those of Spanish . The tilde is used with many letters that are considered part of the alphabet. In the case of Ñ/ñ , it differentiates

540-414: Is a present somewhat aorist : Upe ára resẽ reho mombyry , "that day you got out and you went far". These two suffixes can be added together: ahátama , "I'm already going". This suffix can be joined with -ma , making up -páma : ñande jaikuaapáma nde remimoʼã , "now we came to know all your thought". These are unstressed suffixes: -ta, -ma, -ne, -vo, -mi ; so the stress goes upon

594-697: Is a river in south-central South America, running through Brazil, Paraguay, and Argentina for some 4,880 kilometres (3,030 mi). Among South American rivers, it is second in length only to the Amazon River . It merges with the Paraguay River and then farther downstream with the Uruguay River to form the Río de la Plata and empties into the Atlantic Ocean. The first European to go up

648-561: Is a second official language of the Argentine province of Corrientes since 2004. Guarani is also one of the three official languages of Mercosur , alongside Spanish and Portuguese . Guarani is the most widely spoken Native American language and remains commonly used among the Paraguayan people and neighboring communities. This is unique among American languages; language shift towards European colonial languages (in this case,

702-637: Is inserted. The postverbal portion is -ri for bases ending in -i , and -i for all others. However, in spoken Guarani, the -ri portion of the circumfix is frequently omitted for bases ending in -i . The negation can be used in all tenses, but for future or irrealis reference, the normal tense marking is replaced by moʼã , resulting in n(d)(V) -base- moʼã-i as in Ndajapomoʼãi , "I won't do it". There are also other negatives, such as: ani , ỹhỹ , nahániri , naumbre , naʼanga . The verb form without suffixes at all

756-502: Is often translated as "ex-", "former", "abandoned", "what was once", or "one-time". These morphemes can even be combined to express the idea of something that was going to be but did not end up happening. So for example, paʼirãgue is "a person who studied to be a priest but didn't actually finish", or rather, "the ex-future priest". Some nouns use -re instead of -kue and others use -guã instead of -rã . Guarani distinguishes between inclusive and exclusive pronouns of

810-508: Is practical along the lower course up to the port of Euclides da Cunha , down the chute of the Coroa do Frade, with a length of about 70 km, counting from the mouth into the Paraná river . Navigation is fairly hazardous. Under normal conditions the minimum depth of this stretch may be estimated at 1.5 metres (4.9 ft). For the last 421 km downstream, the course between the mouth and

864-579: Is the least polluted river of the state of São Paulo. The average total gradient of the Paranapanema River, from its sources to its mouth in the Paraná river is 61 cm/km, not considering the first 100 km, where the river descends from the Serra of Paranapiacaba, at an average gradient of 43 cm/km, a value relatively low for a stream with a length of 929 km. The Paranapanema river may be divided into three principal stretches: From its mouth at

918-587: The Jesuit Reductions . Modern scholarship has shown that Guarani was always the primary language of colonial Paraguay, both inside and outside the reductions. Following the expulsion of the Jesuits in the 18th century, the residents of the reductions gradually migrated north and west towards Asunción , a demographic shift that brought about a decidedly one-sided shift away from the Jesuit dialect that

972-467: The Paraná River, to the Grande Falls , a length of 421 km, the average gradient is 29 cm/km. There are widths of more than 200 m, deeper and shallower stretches, widths that reach nearly 800 m. The radii of curvature are in the order of 1.000 m. The course is more or less meandering presenting a complete horizontal equilibrium, with an excess, only of the stretch close to the junction with

1026-544: The Paraná river , where one may notice the existence of moving sand-banks and islands. From the Grande Falls up to the confluence with the Apiaí-Guaçu River , with a length of 328 km, the river descends a total of 210 m. It is not possible to calculate an average gradient on this stretch, because due to the construction of various dams for the provisioning of hydroelectric power, the level will fall abruptly at those dams. The Upper Paranapanema reaches from

1080-553: The Tupi–Guarani branch of the Tupian language family . It is one of the official languages of Paraguay (along with Spanish ), where it is spoken by the majority of the population, and where half of the rural population are monolingual speakers of the language. Variants of the language are spoken by communities in neighboring countries including parts of northeastern Argentina , southeastern Bolivia and southwestern Brazil , and

1134-495: The nasalising tilde . The letter G̃/g̃ , which is unique to this language, was introduced into the orthography relatively recently during the mid-20th century and there is disagreement over its use. It is not a precomposed character in Unicode , which can cause typographic inconveniences – such as needing to press "delete" twice in some setups – or imperfect rendering when using computers and fonts that do not properly support

1188-522: The sábalo ) are commercially important, and they are exploited for heavy internal consumption or for export. The Parana River delta ranks as one of the world's greatest bird-watching destinations. Much of the length of the Paraná is navigable , and the river serves as an important waterway linking inland cities in Argentina and Paraguay with the ocean, providing deepwater ports in some of these cities. The construction of enormous hydroelectric dams along

1242-461: The Guarani spoken outside of the missions was characterized by a free, unregulated flow of Hispanicisms; frequently, Spanish words and phrases were simply incorporated into Guarani with minimal phonological adaptation. A good example of that phenomenon is found in the word "communion". The Jesuits, using their agglutinative strategy, rendered this word " Tupârahava ", a calque based on the word " Tupâ ", meaning God. In modern Paraguayan Guarani,

1296-716: The Paranapanema's reservoirs have considerable influence on the regime of the river in its middle course. In the lower course the influence is reduced, with no effect on the natural conditions that completely impede navigation. The Paranapanema River has in total eight dams and their respective reservoirs. The following table traces a list going in the direction of the Paraná River .

1350-542: The Paraná River was the Venetian explorer Sebastian Cabot , in 1526, while working for Spain. A drought hit the river in 2021, causing a 77-year low. In eastern South America there is "an immense number of river names containing the element para- or parana- ", from Guarani language words meaning "river" or "sea"; attempts to derive a more precise meaning for the name of this, the largest of them, e.g. "kin of

1404-476: The Rio Paraná forms a massive drainage basin that encompasses much of the southcentral part of South America, essentially including all of Paraguay, much of southern Brazil, northern Argentina, and the southeastern part of Bolivia . If the Uruguay River is counted as a tributary to the Paraná, this watershed extends to cover most of Uruguay as well. The volume of water flowing into the Atlantic Ocean through

1458-515: The Río de la Plata roughly equals the volume at the Mississippi River delta . This watershed contains a number of large cities, including São Paulo , Buenos Aires , Rosario , Asunción , Brasília , and La Plata . The Paraná and its tributaries provide a source of income and of daily sustenance for fishermen who live along its banks. Some of the species of fish (such as the surubí and

From the sources to the mouth of the Itararé River , the Paranapaneba flows within the territory of São Paulo state. Below the Itararé the Paranapanema forms the border between the states of Paraná and São Paulo. The river is associated with a date according to State Law 10.488/99 ( Antônio Salim Curiati ), sanctioned by Governor Mário Covas , designated as August 27. The Paranapanema

1566-574: The Spanish and IPA equivalents, although sometimes the open-mid allophones [ ɛ ] , [ ɔ ] are used more frequently. The grapheme ⟨y⟩ represents the vowel / ɨ / (as in Polish ). Considering nasality, the vowel system is perfectly symmetrical, each oral vowel having its nasal counterpart (most systems with nasals have fewer nasals than orals). Guarani displays an unusual degree of nasal harmony . A nasal syllable consists of

This is represented as (C)V . In the below table, the IPA value is shown. The orthography is shown in angle brackets below, if different. The voiced consonants have oral allophones (left) before oral vowels, and nasal allophones (right) before nasal vowels . The oral allophones of

1782-430: The complex layout feature of glyph composition. Only stressed nasal vowels are written as nasal. If an oral vowel is stressed, and it is not the final syllable, it is marked with an acute accent: á, é, í, ó, ú, ý . That is, stress falls on the vowel marked as nasalized, if any, else on the accent-marked syllable, and if neither appears, then on the final syllable. Guarani Braille is the braille alphabet used for

1836-611: The confluence of the Apiaí-Guaçu River to the river's sources in the Serra de Agudos Grandes, with a length of 180 km. The average gradient is quite high, 150 cm/km. It drains a series of streams that descend from the Serra of Paranapiacaba, the Upper Paranapanema is gaining size and consolidates to receive the Itapetininga River and Apiaí-Guaçu river. Navigation of the Paranapanema River

1890-552: The confluence with the Paraguay River, the Paraná again turns to the south for another approximately 820 km (510 mi) through Argentina, making a slow turn back to the east near the city of Rosario for the final stretch of less than 500 km (310 mi) before merging with the Uruguay River to form the Río de la Plata . This flows into the Atlantic Ocean . During the part of its course downstream from

1944-423: The dam of Salto Grande, the average gradient is an about 29 cm/km. The main natural obstacles that interrupt or make navigation dangerous are: a basalt bank, hidden rocks, reduced current velocity, too little depth, a straight canal in the middle of the river, an elevated current velocity, an undulating movement, a sinuous canal, sand banks, and stretches with high gradient. The great reserves of water held in

1998-410: The first person plural. Reflexive pronoun: je : ahecha ("I look"), ajehecha ("I look at myself") Guarani stems can be divided into a number of conjugation classes, which are called areal (with the subclass aireal ) and chendal . The names for these classes stem from the names of the prefixes for 1st and 2nd person singular. The areal conjugation is used to convey that

2052-424: The history of Guarani. There also seems to be some degree of variation between how much the glottal stop is dropped (for example aruʼuka > aruuka > aruka for "I bring"). It is possible that word-internal glottal stops may have been retained from fossilized compounds where the second component was a vowel-initial (and therefore glottal stop–initial) root. /a/, /e/, /i/, /o/, /u/ correspond more or less to

2106-489: The last syllable of the verb or the last stressed syllable. The close and prolonged contact Spanish and Guarani have experienced has resulted in many Guarani words of Spanish origin. Many of these loans were for things or concepts unknown to the New World prior to Spanish colonization . Examples are seen below: English has adopted a small number of words from Guarani (or perhaps the related Tupi ) via Portuguese, mostly

2160-465: The missionaries had curated in the southern and eastern territories of the colony. By and large, the Guarani of the Jesuits shied away from direct phonological loans from Spanish. Instead, the missionaries relied on the agglutinative nature of the language to formulate new precise translations or calque terms from Guarani morphemes. This process often led the Jesuits to employ complicated, highly synthetic terms to convey European concepts. By contrast,

2214-519: The names of animals or plants. " Jaguar " comes from jaguarete and " piraña " comes from pira aña ("tooth fish" Tupi: pirá 'fish', aña 'tooth'). Other words are: " agouti " from akuti , " tapir " from tapira , " açaí " from ĩwasaʼi ("[fruit that] cries or expels water"), " warrah " from aguará meaning "fox", and " margay " from mbarakaja'y meaning "small cat". Jacaranda , guarana and mandioca are words of Guarani or Tupi–Guarani origin. Ipecacuanha (the name of

2268-460: The nasal allophone is always [ ɲ ] . The dorsal fricative is in free variation between [ x ] and [ h ] . ⟨g⟩ , ⟨gu⟩ are approximants, not fricatives, but are sometimes transcribed [ ɣ ] , [ ɣʷ ] , as is conventional for Spanish. ⟨gu⟩ is also transcribed [ɰʷ] , which is essentially identical to [ w ] . All syllables are open, viz. CV or V, ending in

2322-565: The other official language of Spanish ) has otherwise been a nearly universal phenomenon in the Western Hemisphere , but Paraguayans have maintained their traditional language while also adopting Spanish. Jesuit priest Antonio Ruiz de Montoya , who in 1639 published the first written grammar of Guarani in a book called Tesoro de la lengua guaraní (Treasure/ Thesaurus of the Guarani Language) , described it as

2376-517: The palatal nasal from the alveolar nasal (as in Spanish), whereas it marks stressed nasalisation when used over a vowel (as in Portuguese ): ã, ẽ, ĩ, õ, ũ, ỹ . (Nasal vowels have been written with several other diacritics: ä, ā, â, ã .) The tilde also marks nasality in the case of G̃/g̃ , used to represent the nasalized velar approximant by combining the velar approximant G with

2430-665: The participant is actively involved , whereas the chendal conjugation is used to convey that the participant is the undergoer . However, the areal conjugation is also used if an intransitive verb expresses an event as opposed to a state , for example manó 'die', and even with a verb such as ké 'sleep'. In addition, all borrowed Spanish verbs are adopted as areal as opposed to borrowed adjectives, which take chendal . Intransitive verbs can take either conjugation, transitive verbs normally take areal , but can take chendal for habitual readings. Nouns can also be conjugated, but only as chendal . This conveys

2484-706: The river is dammed by the Itaipu Dam, the third largest hydroelectric power plant in the world (following the Three Gorges Dam and the Baihetan Dam , both in the People's Republic of China ), creating a massive, shallow reservoir behind it. After merging with the Iguazu, the Paraná becomes the natural border between Paraguay and Argentina. Overlooking the Paraná River from Encarnación, Paraguay , across

2538-493: The river's length has blocked its use as a shipping corridor to cities further upstream, but the economic impact of those dams offsets this. The Yacyretá Dam and the Itaipu Dam on the Paraguay border have made the small, largely undeveloped nation of Paraguay the world's largest exporter of hydroelectric power . Due to its use for oceangoing ships, measurements of the water tables extend back to 1904. The data correlates with

2592-469: The river, is downtown Posadas, Argentina. The river continues its general southward course for about 468 km (291 mi) before making a gradual turn to the west for another 820 km (510 mi), and then encounters the Paraguay River , the largest tributary along the course of the river. Before this confluence, the river passes through a second major hydroelectric project, the Yacyretá Dam ,

2646-595: The same word is rendered " komuño ". Following the out-migration from the reductions, these two distinct dialects of Guarani came into extensive contact for the first time. The vast majority of speakers abandoned the less colloquial, highly regulated Jesuit variant in favor of the variety that evolved from actual use by speakers in Paraguay. This contemporary form of spoken Guarani is known as Jopará , meaning "mixture" in Guarani. Widely spoken, Paraguayan Guarani has nevertheless been repressed by Paraguayan governments throughout most of its history since independence. It

2700-526: The sea", have been discounted. The course is formed at the confluence of the Paranaiba and Rio Grande rivers in southern Brazil. From the confluence the river flows in a generally southwestern direction for about 619 km (385 mi) before encountering the city of Saltos del Guaira , Paraguay. This was once the location of the Guaíra Falls (Sete Quedas waterfalls, where the Paraná fell over

2754-605: The subject is not specified. The language lacks gender and has no native definite article but, due to influence from Spanish, la is used as a definite article for singular reference and lo for plural reference. These are not found in Classical Guarani ( Guaraniete ). Guarani exhibits nominal tense: past, expressed with -kue , and future, expressed with -rã . For example, tetã ruvichakue translates to "ex-president" while tetã ruvicharã translates to "president-elect." The past morpheme -kue

2808-405: The voiced stops are prenasalized . There is also a sequence /ⁿt/ (written ⟨nt⟩ ). A trill /r/ (written ⟨rr⟩ ), and the consonants /l/ , /f/ , and /j/ (written ⟨ll⟩ ) are not native to Guarani, but come from Spanish. Oral /ᵈj/ is often pronounced [ dʒ ] , [ ɟ ] , [ ʒ ] , [ j ] , depending on the dialect, but

2862-487: Was established in the new constitution as a language equal to Spanish. Jopará, the mixture of Spanish and Guarani, is spoken by an estimated 90% of the population of Paraguay. Code-switching between the two languages takes place on a spectrum in which more Spanish is used for official and business-related matters, and more Guarani is used in art and in everyday life. Guarani is also an official language of Bolivia and of Corrientes Province in Argentina. Guarani became

2916-423: Was prohibited in state schools for over 100 years. However, populists often used pride in the language to excite nationalistic fervor and promote a narrative of social unity. During the autocratic regime of Alfredo Stroessner , his Colorado Party used the language to appeal to common Paraguayans although Stroessner himself never gave an address in Guarani. Upon the advent of Paraguayan democracy in 1992, Guarani
