Rob’s question: “Is ‘thank you’ a hyphenated word? For example, should I write ‘thank you for your help’ or ‘thank-you for your help’?”
BizWritingTip response: To express gratitude use the two words thank you – without the hyphen.
Thank you for your help.
If you are familiar with British English, you probably learned to write thank-you. However, several years ago, hyphens were dropped from many English words, e.g., bumble-bee, ice-cream, and thank-you.
The only time you should use a hyphen with the word is when you are using it as an adjective.
I need to send them a thank-you gift.
Did you send a thank-you card?
Thank you for reading.
