triennial

Occurring every three years. / An event that happens every three years.
形容詞名詞
複数形: triennials

Triennial is a formal term used to describe events or cycles that repeat every three years. It is most commonly found in professional, academic, or governmental contexts, such as strategic planning, international summits, or specialized art exhibitions. In casual conversation, native speakers are more likely to say "every three years" rather than using this specific adjective.

It belongs to a family of Latin-derived frequency terms. It is often contrasted with biennial (every two years) and quadrennial (every four years). Because these terms sound similar, they are frequently confused in professional writing; however, triennial specifically denotes a three-year interval.

When used as a noun, it refers to the event itself (e.g., "The triennial was a success"). When used as an adjective, it modifies the event or the cycle (e.g., "a triennial report"). The noun form is less common than the adjective form but is standard when referring to established recurring festivals or conferences.
