* A misspelling of a similar word. Can you double-check the spelling?
* A regional word from a specific language or dialect. If you know the language or region where you heard it, that would help.
* A slang term or nickname that isn't widely used.
To help me understand what you're looking for, could you please provide more context? For example:
* Where did you hear the word "chavala"?
* What was the context in which it was used?
* What language do you think it's from?
With more information, I can try to figure out what "chavala" means.
