Biweekly or Bi-Weekly: Which is Correct?

The term “biweekly” means something that happens every two weeks or twice in one week. It’s a word you’ll often see in situations like work schedules, loan repayments, or meetings. Sometimes, though rarely, it’s used to describe things that occur twice in a single week.

You might be confused whether to use biweekly or bi-weekly. Should it be one word, or should you split it into two? Should you use a hyphen or not?

So, what’s the right way to write it? Is it “Bi Weekly”, “Biweekly”, or “Bi-Weekly”?

The single-word form ‘biweekly’ is generally more widely accepted and used.

Biweekly or Bi-Weekly: Which is Correct?

The term biweekly without a hyphen is the correct form.

According to the Oxford English Dictionary, biweekly refers to anything that is produced or happens every two weeks or twice each week. 

It can be used as both adjective and an adverb.

  • Adjective: We have biweekly meetings to discuss project updates
  • Adverb: The newsletter is published biweekly

The word itself is comprised of two parts: bi-, meaning two, and weekly, which means every week. Therefore, the word biweekly is a combination of these two words to indicate something happening every two weeks or twice in one week.

Why there is no hyphen in biweekly?

The prefix bi- is possibly the source of the confusion around the use of hyphen when writing the word biweekly.

A hyphen (-) is a little dash that is sometimes used in English words to link separate words together, like in “mother-in-law” or “well-known.” 

But we don’t always need a hyphen when we use a prefix like “bi-.”

This is because, generally, you don’t need to use a hyphen with a word that has a prefix. Examples include ‘bipolar’, ‘unhappy’, ‘prepaid’, ‘reconsider’, etc. 

So, “biweekly” is correct when written without a hyphen because it follows the rules of English writing.
