Distinction is made between the two major standards of the language—Portugal (European Portuguese, EP; broadly the standard also used in Africa and Asia) and Brazil (Brazilian Portuguese, BP). Neither variant is preferred at Wikipedia, except in cases where a local pronunciation is clearly more relevant, such as a place in Brazil or an individual from Portugal.

National variant differences should be noted with discretion. When there are differing dialectal Brazilian Portuguese pronunciations, the one closest to European Portuguese should generally be preferred, as this guide is intended to help native speakers of other languages.
