Question

Biannual is

• A. once in two years
• B. every year
• C. twice a year
• D. after every two years

Hint:

Bi means two, so think about how many times a year this happens.

Answer 1

The Correct Option is C

This question often trips people up because biannual and biennial sound alike but mean different things, so check the word parts carefully.

1. once in two years: this is the meaning of biennial, a separate word, not biannual.
2. every year: this describes annual, which happens only once a year, missing the bi part entirely.
3. twice a year: this matches biannual exactly, since bi means two events within one annual cycle.
4. after every two years: this again describes biennial, confusing the two similar-sounding words.

So option C, twice a year, is the correct meaning of biannual.

Let's summarize:

• Biannual means twice within one year.
• Biennial, a different word, means once every two years.

Keeping these two words separate in memory avoids the common mix-up in such questions.
