Is it possible to lie without saying a word?

Yup!! Body language can show whether or not you are lying, sometimes looking down or looking around might hint that someone is lying. Increased sweating might also indicate someone is lying. Is that what you meant??

Maybe, if you use you're expressions on you're face. And you said "saying a word", they can text to or do sighn laungage.
