How do you spell the sound a yawn makes?

There's no single agreed-upon spelling for the sound a yawn makes! Here are some options, though:

* Aah - This is a common and simple way to represent the sound.

* Yawwn - This spelling is a bit more descriptive, trying to capture the drawn-out nature of the sound.

* Yawn - Some people simply use the word "yawn" itself to represent the sound.

* Haawwn - This spelling tries to capture a more guttural quality of the sound.

Ultimately, the best way to represent the sound of a yawn is through your own imagination!
