Portuguese: A Western Romance Language of Iberian and Colonial Reach

Portuguese developed from Vulgar Latin in the Iberian Peninsula's northwestern Galician region, becoming a distinct literary language by the twelfth and thirteenth centuries as Portugal established itself as an independent kingdom, and belongs to the West Iberian Romance branch alongside Spanish, Galician and Asturian, with which it retains significant mutual intelligibility reflecting shared medieval origins. Portuguese maritime exploration and colonization from the fifteenth century carried the language across Brazil, parts of Africa including Angola, Mozambique and Guinea-Bissau, and enclaves in Asia including Goa and Macau, making Brazilian Portuguese speakers today vastly outnumber speakers in Portugal itself and giving the language its status as one of the world's most widely spoken by native speakers.

Brazilian and European Portuguese have diverged noticeably in pronunciation and some vocabulary since colonial separation, comparable to differences between American and British English, while remaining a single language for most practical and literary purposes, and Portuguese remains an official language across a substantial community of nations spanning four continents as a direct legacy of the Portuguese maritime empire.
