Someone who's brutish is uncivilized in some way. A brutish person might, for example, knock a table over when he's angry or slap another person without a thought. Brutish leaders make decisions that endanger or even kill people. The word brutish means "like a brute," and a brute is an extremely violent or wild person or animal. In the 1500's, brutish simply meant "like an animal," and the Latin root word, brutus, means "heavy, dull, or stupid."
