A bairro (Portuguese pronunciation: [ˈbajʁu]) is a Portuguese word for a quarter or a neighborhood or, sometimes, a district which is within a city or town. It is commonly used in Brazil, Mozambique, Guinea-Bissau, Portugal, and other Portuguese-speaking places. Bairro is cognate with Germanic berg, burg, borg, burgh, borough etc., and Spanish barrio, all of which descend from the same Proto-Indo European root.
