I have a character who gets his tongue cut off. About how far back would his tongue have to be cut in order to stop him from being able to speak? (Speak clearly, at least--if he tried, he should still be able to talk, though it'd be hard to understand, right?) After it's been cut, how would he stop the bleeding? (He lives in a time period like the Middle Ages, if that helps.)
Also, I've read that the tongue aids swallowing. Would there be any problems with that after it's cut out?
If there are other problems he'll have, feel free to tell me. I'd greatly appreciate it. :D
Thanks in advance!
