The word "frequency" originates from the Latin frequentia, meaning "a crowding or assembling in large numbers." The root frequent- (from Latin frequens) carries the sense of "repeated or occurring often," while the suffix -cy (via Latin -tia) forms abstract nouns indicating a state or condition. Over time, the term evolved in scientific contexts to denote the regularity of recurring events, particularly in physics and statistics.
