Portuguese language

Portuguese (endonym: português or língua portuguesa) is a Western Romance language of the Indo-European language family originating from the Iberian Peninsula of Europe. It is spoken chiefly in Portugal, in Brazil, and in several African countries, as well as by immigrants in North America, Europe, and South America. With approximately 267 million speakers, it is listed as the fifth-most spoken native language.

Portuguese-speaking people or nations are known as Lusophone (lusófono). As a result of expansion during colonial times, a cultural presence of Portuguese speakers is also found around the world. Portuguese is part of the Ibero-Romance group, which evolved from several dialects of Vulgar Latin in the medieval Kingdom of Galicia and the County of Portugal, and has retained some Celtic phonology.

Portuguese language structure reflects both its Latin roots and centuries of outside influences. These are seen in phonology, orthography, grammar, and vocabulary. Phonologically, Portuguese has a rich system of nasal vowels, complex consonant variations, and different types of guttural R - as well as other sounds in its European and Brazilian varieties. Its spelling, based similarly to English on the Latin alphabet, is largely phonemic but is influenced by etymology and tradition. Recent spelling reforms have attempted to create a unified spelling for the Portuguese language across all countries that use it. Portuguese grammar retains many Latin verb forms, and possesses several unique features (such as the future subjunctive and the personal infinitive). Its vocabulary is derived largely from Latin, but also includes numerous loanwords from Celtic, Germanic, Arabic, African, Amerindian, and Asian languages, resulting from historical contact based on wars, trade, and colonization.

There is significant variation in the dialects of Portuguese worldwide, with two primary standardized varieties: European Portuguese and Brazilian Portuguese, each one having numerous regional accents and subdialects. African and Asian varieties generally follow the European written standard, though these will often display different phonological, lexical, and sometimes even syntactic features. While there is broad mutual intelligibility among the assorted lusophone population, variation may be observed in speech patterns, vocabulary, or grammar.
