Portuguese (português) is the official language of Portugal, Brazil, Mozambique, Angola, Cape Verde, Guinea-Bissau, and São Tomé and Príncipe. Portuguese is a part of the Ibero-Romance group that evolved from several dialects of colloquial Latin in the medieval Kingdom of Galicia. Portuguese is usually listed as the seventh most spoken language in the united states, 1st in South america and the third European language most spoken in the world. Most of the lexicon of Portuguese is derived from Latin. A notable aspect of the grammar of Portuguese is the verb. Morphologically, more verbal inflections from classical Latin have been preserved by Portuguese than by any other major Romance language. Portuguese is written with 26 letters of the Latin script, making use of five diacritics to denote stress, vowel height, contraction, nasalization, and other sound changes.
