Here's why it might be confusing:
* Incomplete phrase: It's likely a fragment of a larger phrase that is missing context. For example, it could be "you sound it out," which would mean to pronounce a word slowly and carefully.
* Regional dialect: The phrase might be specific to a certain region or community where it has a unique meaning.
* Misheard phrase: You might have misheard a similar-sounding phrase.
To understand what someone means by "you sound it," you'll need more information:
* Context: What was the situation when someone said it? What were they talking about?
* Tone of voice: Was the person being serious, sarcastic, or playful?
If you can provide more context, I might be able to help you figure out what they meant.
