existido

Existido is the past participle of the Portuguese verb existirexistir. It is used mainly in compound tenses with auxiliary verbs such as haver or ter, and can also function as an adjective in certain constructions. In contemporary usage, the preferred ways to express existence up to the present are forms like há existido or tem existido.

Etymology and forms: Existir comes from the Latin existere, from ex- (out) + sistere (to stand). The participle exists in gender and number agreements when used as an adjective (existido, existida, existentes, existidas) and remains as a non-agreeing form in most periphrastic constructions with ter or haver. The standard present-day sense is to indicate something that has existed at least once or continues to exist up to the present moment.

Usage notes: In everyday Portuguese, speakers frequently prefer other words such as existente or que existe to describe something that currently exists. Existido appears more often in formal, historical, or technical registers, and in periphrastic phrases using haver or ter to emphasize the duration or occurrence of existence. Common fixed expressions include há existido and tem existido, which convey that existence has occurred or persisted up to now.
