Common Mistakes

Using “anytime” directly after a preposition like “at,” where the two-word form is required — “at anytime” is always incorrect.

Using “any time” in casual adverb contexts where “anytime” would be simpler and more natural, like “call me any time” (technically fine but more formal).

Assuming the two forms are always interchangeable — they aren’t when a preposition is involved.

The Preposition Rule

This is the one rule that removes all guesswork: whenever a preposition comes directly before the phrase — “at any time,” “in any time,” “for any time” — you must use the two-word form. The one-word “anytime” can never follow a preposition.

Expert Tip 💡

If you’re unsure which to use, default to the two-word form, “any time” — according to ProWritingAid, it’s correct in every context, even where “anytime” would also work, making it the safer choice for formal writing.
