doida

Doida is the feminine form of the Portuguese adjective doido. In standard Portuguese, doido means crazy or insane, but in informal use it is also applied to describe things or people as extreme, unusual, or lively. Doida is widely used in Brazilian Portuguese to describe a female subject, though it appears in other dialects as well.

Grammar and usage: As an adjective, doida agrees with the noun (uma pessoa doida; duas pessoas doidas). It can function attributively (“Ela é doida”) or predicatively (“Ela está doida”). It also appears as a noun phrase in colloquial speech, referring to a person perceived as eccentric or impulsive (“uma doida”). Expressions such as “ideia doida” (a crazy idea) or “festa doida” (a wild party) are common.

Connotations: The tone depends on context and intonation. It can be affectionate or humorous among friends, but may be insulting if used to stigmatize mental health. The term is informal and typically not used in formal writing.

Variants and related terms: The masculine form is doido, with diminutives such as doidinho or doidinha. Related nouns like doidice refer to craziness or folly. Regional slang patterns influence the nuance, with stronger or milder connotations across communities.
