    • Correct: I have twice-weekly classes on Mondays and Fridays.

  2. Misusing bimonthly for twice a month without clarification:

    • Incorrect: Our newsletter is bimonthly (but you mean twice a month).

Everyday Use

  • Biweekly: This is most often used to describe something that happens every other week, like a paycheck or a meeting.
