Fechadas

Fechadas is the feminine plural form of the Portuguese adjective fechada, used to indicate that something is closed, not open, or inaccessible. The term appears in everyday language to describe physical objects such as portas e janelas, as well as establishments or events that are not open to the public, and in figurative expressions to convey inaccessibility or exclusivity.

The word derives from the verb fechar (to close) and shares its semantic range with other related expressions. In addition to describing tangible closures, fechadas is used in phrases that convey a closed mindset or restricted access, such as mentes fechadas (closed minds) or regras fechadas (strict or closed rules). It also occurs in contexts that emphasize confinement or restriction, like reuniões fechadas (closed-door meetings).

In common usage, fechadas often appears with feminine nouns, for example: portas fechadas, lojas fechadas, or reuniões fechadas. When referring to masculine nouns, the corresponding form is fechados, such as portos fechados or mercados fechados.

In mathematics, the term is used in the feminine form to describe certain objects. For instance, curvas fechadas (closed curves) and superfícies fechadas (closed surfaces) refer to entities that contain all their boundary points in a given topology. This usage parallels other specialized domains where the notion of closure is central.

Fechadas thus covers a range of meanings tied to the idea of closure, from everyday physical states to abstract concepts in science and mathematics. See also fechada, fechado, and fechar.
