Spelling Tips: Cosy or Cozy?

‘Cosy’ and ‘cozy’ are two spellings of the same adjective, which is used to describe something that gives a feeling of warmth and comfort. But does it matter whether you write about a ‘cosy log cabin’ or a ‘cozy log cabin’?

In this post, we explain the difference between these two spellings.

Australian English vs. American English

‘Cosy’ is the preferred spelling in Australian English, while ‘cozy’ is used in American English. Which spelling to use, therefore, depends on which dialect you are using:

Australian English: The cat slept in its cosy basket.

American English: The cat slept in its cozy basket.

You can also use ‘cosy’ or ‘cozy’ as a noun. In this case, it refers to a soft covering used to keep something warm (usually a teapot or a boiled egg):

Australian English: You should use a cosy if you want your tea to stay hot.

American English: You should use a cozy if you want your tea to stay hot.

And in case you’re writing for a UK audience, British English also uses ‘cosy’.
