Portuguese language

Portuguese language is a Romance language and the sole official language of Portugal, Brazil, Mozambique, Angola, Cape Verde, Guinea-Bissau, and São Tomé and Príncipe.
Classification and related languages following members of this group:
Galician, Fala and portunhol da pampa (the way riverense and its sibling dialects are referred to in Portuguese), its closest relatives.
Mirandese, Leonese, Asturian, Extremaduran and Cantabrian (Astur-Leonese languages). Mirandese is the only recognised regional language spoken in Portugal (beside Portuguese, the only official language in Portugal).
Spanish and calão (the way caló, language of the Iberian Romani, is referred to in Portuguese).
 Communication is quite good between monolingual Brazilians and Spanish-speaking Latin Americans; between monolingual Portuguese and Spanish-speaking Spaniards the accents can make things more challenging. However, educated Portuguese and Spaniards can usually understand one another quite well. And portunhol, a form of code-switching, has far more users in the Americas (not to be confused with the portunhol spoken in the borders of Brazil with Uruguay and Paraguay, that is a Portuguese dialect heavily influenced by Spanish rather than code-switching).


Influence on other languages

Portuguese has provided loanwords to many languages, such as Indonesian, Manado Malay, Malayalam, Sri Lankan Tamil and Sinhalese, Malay, Bengali, English, Hindi, Swahili, Afrikaans, Konkani, Marathi, Tetum, Xitsonga, Papiamentu, Japanese, Lanc-Patuá (spoken in northern Brazil), Esan and Sranan Tongo (spoken in Suriname). It left a strong influence on the língua brasílica, a Tupi–Guarani language, which was the most widely spoken in Brazil until the 18th century, and on the language spoken around Sikka in Flores Island, Indonesia. In nearby Larantuka, Portuguese is used for prayers in Holy Week rituals. The Japanese–Portuguese dictionary Nippo Jisho (1603) was the first dictionary of Japanese in a European language, a product of Jesuit missionary activity in Japan. Building on the work of earlier Portuguese missionaries, the Dictionarium Anamiticum, Lusitanum et Latinum (Annamite–Portuguese–Latin dictionary) of Alexandre de Rhodes (1651) introduced the modern orthography of Vietnamese, which is based on the orthography of 17th-century Portuguese. The Romanization of Chinese was also influenced by the Portuguese language (among others), particularly regarding Chinese surnames; one example is Mei. During 1583–88 Italian Jesuits Michele Ruggieri and Matteo Ricci created a Portuguese–Chinese dictionary—the first ever European–Chinese dictionary


Derived languages

Beginning in the 16th century, the extensive contacts between Portuguese travelers and settlers, African and Asian slaves, and local populations led to the appearance of many pidgins with varying amounts of Portuguese influence. As each of these pidgins became the mother tongue of succeeding generations, they evolved into fully fledged creole languages, which remained in use in many parts of Asia, Africa and South America until the 18th century. Some Portuguese-based or Portuguese-influenced creoles are still spoken today, by over 3 million people worldwide, especially people of partial Portuguese ancestry.
