Frequently Asked Questions

Is it "thank you" or "thankyou"?

In standard English it is two words: thank you. "Thankyou" as a single word is a common misspelling, though it does appear informally in some Australian and British usage. Use the hyphenated "thank-you" only when it works as a noun or adjective, as in "a thank-you card".

What is the difference between "thank you" and "thanks"?

They mean the same thing, but "thank you" is slightly more formal and more emphatic, while "thanks" is casual and quicker. Use "thank you" in writing, with strangers, or when the favour was substantial; "thanks" is fine among friends and colleagues.

How do you reply to "thank you"?

The standard replies are "you're welcome", "no problem", "my pleasure" or simply "of course". In British English "not at all" and "don't mention it" are also common and slightly more formal.
