semiannual

Imagine something that comes around two times in one year, with about six months between each time. That is what semiannual means. You will often see it in business, finance, and official schedules. A company might publish a semiannual report, a bank might make semiannual interest payments, or a team might hold semiannual meetings. It happens more often than something annual, but less often than something quarterly.

The word semiannual comes from the Latin prefix semi-, meaning "half," and annual, meaning "yearly." So, literally, it means "half-yearly." It describes something that occurs twice in one year, usually at six-month intervals.

While you might hear it used to describe any event happening twice a year—like a semiannual family reunion or a semiannual cleaning spree—it's most commonly found in formal contexts, particularly in business, finance, and government. Companies often release semiannual reports detailing their financial performance. Banks might offer semiannual interest payments on certain accounts. Government agencies may hold semiannual public hearings.

It's important to distinguish semiannual from biennial, which means happening every two years, and annual, which means happening once a year. If your car requires a safety inspection, it might be annual. If a certain flower only blooms every other year, it's biennial. But if you're expected to submit progress reports on a project twice each year, those are semiannual reports.

So, when something happens roughly every six months, remember the semi- prefix and think "half-year"—that's what makes an event semiannual.
