Use as a Noun or Adjective

Thank you when used as a noun or adjective often remains as two separate words. For instance:

  • I sent a thank you card to my friend.
  • Your thank you note was very thoughtful.

The Single Word Form

It’s acknowledgment that the term thankyou used as a single word is gaining prevalence, particularly as a noun or an adjective. However, this form is still considered more commonplace in informal writing. Some examples include:

  • She left a thankyou note.
  • The company gave me a bonus as a thankyou for my hard work.

Hyphenated Form

In some instances, you might see thank-you written with a hyphen, especially when it’s used as a noun or adjective. Nonetheless, it’s generally inadmissible in formal writing. Here are examples:

  • The auction includes a thank-you note from the scholar.
  • He scribbled a quick thank-you on the post-it.


In conclusion, to answer the question – is thank you one word or two? The answer primarily depends on its usage. As a verb phrase or formal writing, choose thank you. As a noun or adjective in informal writing, either thank you, thankyou, or thank-you can be applicable. However, it’s recommended to stick to two words – thank you – as it’s most widely accepted and less prone to error in various contexts.
