frequent

Frequent is an adjective describing something that occurs often or is common over a given period. It denotes a high rate of occurrence or regularity, as in frequent appointments, frequent delays, or a frequent traveler. The word is used with nouns to express degree of recurrence; its adverb form is frequently, as in "they meet frequently." The comparative form is more frequent and the superlative most frequent.

As a verb, to frequent means to visit a place regularly or habitually. It can also describe spending a noticeable amount of time in a location. Examples: "He frequents the library after work" or "The café was frequented by students." The verb is distinct from the adjective and is less about the frequency of events and more about habitual presence.

In statistics and related fields, the term frequency describes how often a value occurs within a data set. The adjective frequent appears in the related term frequentist, which refers to interpretations of probability grounded in observed long-run frequencies rather than beliefs about single events.

Etymology: Frequent derives from Middle English frequent, from Old French frequent, and ultimately from Latin frequens, frequ- meaning "crowded, occurring often."
