When we talk about “primitive man”, we’re usually talking about cavemen and other people who existed before the advent of table manners, but if your uncle speaks grunts and chews with his mouth open, you could describe him as primitive too.
Primitive is related to the word prime, and the root of both words is primus, which is Latin for “first.”
