How do you spell scheww?

"Scheww" is not a standard English word. It's likely a phonetic spelling of a sound or a word that doesn't have a standard spelling.

To help me understand what you're trying to spell, could you provide more context?

For example:

* What word are you trying to spell?

* What sound are you trying to represent?

* Where did you hear or see this spelling?

With more information, I can give you a more accurate answer.
