Did You Know?

Biennial conventions, celebrations, competitions, and sports events come every two years. Biennials are plants that live two years, bearing flowers and fruit only in the second year. (Carrots and sugar beets are two examples; since we're only interested in their roots, we don't wait another year to see their flower and fruit.) In contrast, semiannual means "twice a year". But no one can agree whether biweekly means "twice a week" or "every two weeks", and whether bimonthly means "twice a month" or "every two months". Maybe we should stop using both of them until we can decide.

Word Root of biennial

The Latin word annus, meaning “year,” gives us the root ann or enn. Words from the Latin annus have something to do with a year. Anything that is annual happens once a year and anything biennial happens once every two years. An anniversary is the return every year of the date on which something special happened. Something perennial continues all year long or comes back each year.
