English

Adjective

triannual ‎(not comparable)

1. Happening three times each year.

Usage notes

• To avoid confusion between "triennial," once every three years, and "triannual," three times in one year, it is often better to substitute a less ambiguous phrase such as "three times a year" or "every four months."
