abertas

Abertas is a word in Portuguese that functions primarily as the feminine plural form of the adjective aberto/aberta, meaning open. It can describe feminine plural nouns, as in portas abertas (open doors) or janelas abertas (open windows). In standard usage, when referring to an opening or gap as a noun, the form abertura (singular) or aberturas (plural) is more common, while abertas is used to agree with the gender and number of the nouns it modifies.

In everyday language, abertas appears in phrases that convey openness both literally and figuratively. Examples include situações abertas (open situations) or mentes abertas (open minds), where the term expresses accessibility, receptivity, or lack of barriers. The word can also appear in signage or descriptions indicating that something is currently accessible or not closed, such as portas abertas on a building or venue.

Etymology traces abertas to aberto, which derives from Latin aperire, meaning to open. The feminine plural relação abertura aligns with the general Romance-language pattern of gendered adjective agreement. While abertas itself is common in ordinary speech and writing, references to it as a standalone noun are limited; when referring to an opening as a noun, palavras like abertura or fresta are more typical.

See also: aberto, abertura, aberturas, mente aberta. Abiertas is sometimes encountered in Brazilian Portuguese as part of larger phrases, but does not denote a distinct geographical or organizational term on its own.
