If you remember this distinction, you’ll instantly reduce confusion in your writing.
Historical Background & Origins
The roots of these words go back centuries.
- Any time as two words is literal: it refers to any specific amount of time. It appears in texts as early as the 16th century in English literature. Writers like Shakespeare occasionally used the phrase to mean whenever needed.
- Anytime as a single word evolved in the 19th century as English began blending noun phrases into adverbs. Its main function is conversational—used to mean at any moment or whenever convenient.
Fun Fact: Even though “anytime” is widely accepted today, style guides like Chicago Manual of Style recommend reserving the single-word form for informal contexts.
British English vs American English
Spelling and usage can differ slightly between the UK and the US:
- In American English, “anytime” as one word is widely accepted in both informal and semi-formal writing.
- In British English, “any time” (two words) is preferred in formal writing. “Anytime” still appears in casual contexts, but it’s less frequent.
Example:
- US English: “You can call me anytime.”
- UK English: “You can call me at any time.”
This subtle difference matters if you write for international audiences, academic papers, or professional documents.
When to Use “Any Time”
Use any time (two words) when you’re talking about an amount of time.
Guidelines:
- Works with prepositions like at, for, in.
- Often appears in formal writing or professional emails.
- Can describe a specific or general timeframe.
Examples:
- “I can meet with you at any time this week.”
- “You are free to use the conference room for any time you need.”
- “Any time spent learning a new skill is never wasted.”
Tip: If you can replace the phrase with “any amount of time”, then use two words.
When to Use “Anytime”
Use anytime (one word) when you mean whenever—it’s an adverb describing the moment something happens.
Guidelines:
- Common in casual writing, emails, or speech.
- Often follows a verb.
- Never requires a preposition.
Examples:
- “You can reach out to me anytime.”
- “Feel free to drop by anytime.”
- “Anytime you want, we can start the project.”
Quick Trick: If you can replace it with “whenever”, use anytime.
