Brazilian given names draw primarily from Portuguese, with standard gendered endings such as masculine -o (Paulo, Márcio) and feminine -a (Ana, Luísa). Diacritics are common and orthographically significant, as in João, Antônio, and José. Compound first names are widespread, especially Maria and Ana for girls and João and José for boys (for example Maria Clara, Ana Beatriz, João Pedro). Catholic and biblical naming has been historically dominant, though Portuguese forms often differ from Spanish: Miguel, Gabriel, Rafael, Mateus. Informal diminutives use -inho and -inha (Paulinho, Aninha), though these are usually nicknames rather than official names.
Brazilian usage mixes sources and styles. Indigenous Tupi-Guarani names appear (Iara, Moema), and some African-origin names and theonyms occur regionally. Since the 20th century, Brazil has also favored -son endings and English-influenced forms (Robson, Jefferson), alongside Portuguese-Germanic endings like -aldo and -valdo (Ronaldo, Osvaldo). Contemporary trends include creative spellings with y, h, and doubled letters (Rayssa, Thaynara), and the productive -iel/-iel masculine pattern (Daniel, Muriel, Ezequiel). There is no single defining pattern; Brazilian naming shows layered Portuguese roots with indigenous, African, and international influences.
