Anytime vs. Any Time

Anytime vs. Any Time: the Definitions

ANYTIME is an adverb that means “at any time”, and it also can be a conjunction that means “whenever”. ANY TIME is a phrase that has pretty much the same meaning. In fact, anytime as a word first appeared in the dictionaries only in the 1930s. Before that, in all the contexts that this word is used today, any time was used without any problems.


  • You are welcome to visit the school anytime; we have an open-door policy.
  • The chairman may adjourn the meeting at any time.

How to Use Anytime or Any Time Correctly?

In most cases, any time and anytime are interchangeable. However, sometimes it’s logical to use the two-word version. For example, if you form the phrase “at any time”, you can’t spell “any time” as one word because this phrase won’t make sense with an adverb instead of a noun. Or, if you’re in a hurry, you will say, “I don’t have ANY TIME to spare”, not “I don’t have ANYTIME to spare”. The reason is the same: this sentence needs a noun, not an adverb.

To feel safe, you should prefer to use any time in all of your writing, especially formal. Many British dictionaries don’t even have the word anytime in them, and where this word exists, it’s often called a casualismAny time, spelled as two separate words, doesn’t create arguments, and it’s been used for a lot longer than its one-word version. So, there’s no reason why you shouldn’t use it as well.
