asiduos

Asiduos is a Spanish adjective and noun. As an adjective, it describes people or actions marked by regularity, constancy, and sustained effort. When used of people, it conveys diligence and habitual presence; for activities or habits, it emphasizes persistence. The masculine plural is asiduos, the feminine plural asiduas, with the singular forms asiduo (masc.) and asidua (fem.).

As a noun, asiduos refers to regulars or frequent attendees in a group, club, or institution, for example, los asiduos del café or los asiduos del museo. The term thus captures the idea of people who attend or participate consistently over time.

Etymologically, asiduos derives from Latin assiduus, meaning constant or attentive, and it is related to the noun asiduidad, which denotes assiduity or diligence. The adverbial form asiduamente is used to describe actions done with regularity or persistence.

Common usage includes describing readers, workers, or participants who show steady engagement: “un lector asiduo,” “un empleado asiduo,” or “los asiduos asistentes.” It is often contrasted with terms that imply irregularity or infrequency.

See also: asiduidad (assiduity), asiduamente (assiduously), constante, diligente, perseverante, fiel. While similar to these, asiduos emphasizes habitual presence and persistent effort, rather than merely occasional reliability.
