Official name brazil
In English, the country is conventionally called Brazil. In Portuguese, its official name is República Federativa do Brasil, usually translated as Federative Republic of Brazil. “Brasil” is the Portuguese spelling.
How it works
The country’s short-form name in Portuguese is Brasil, while the English spelling adapts the final letter to English orthography. Both refer to the same South American country in their respective language contexts.

Example or application
An English-language map generally labels the country Brazil; a Portuguese-language source uses Brasil. Formal documents may use the longer official name.
Scope and limits
Spelling depends on language and style. When quoting a government source or writing in Portuguese, retain Brasil.
