Writing Tip 160: “Anytime” vs. “Any Time”
“Anytime” is a relatively new word—yes, we’re calling early 20th century “recent” for the sake of this linguistic argument. And you know that any time there is a new word, there’s going to be a grammarian hullaballoo. Here’s just another example.
“Anytime” (one word) is considered a casual form, not one for your résumé or emails to advance you up the corporate ladder. In fact, this one-word form is still not recognized by some dictionaries. (I’m looking at you, OED). “Anytime” technically is defined as an adverb meaning “whenever” or “on any occasion,” but as a new word, it is young and defiant, having other meanings too. “Anytime” can also simply mean “No problem,” in response to a “thank you.”
If you aren’t sure if you can get away with “anytime” vs. “any time,” ask yourself if you can replace the word in question with “at any time.”More
