Usage
What does beastly mean? Beastly is used to describe a person or behavior that’s nasty, vile, or cruel. The word beast sometimes simply means a large animal, but it’s also often used to refer to a kind of monster. This sense of the word is sometimes used figuratively to refer to a person in a way that likens them to a monster and implies that they behave in a crude, brutish, or animalistic way. This is often what’s implied by the word beastly. Beastly can also mean unpleasant or disagreeable, as in beastly weather. In British English, beastly is sometimes used as an informal intensifier to mean very, extremely, or outrageously, as in It’s beastly cold out there or That was a beastly rude thing to do. In this case, beastly is used as an adverb, rather than an adjective. Example: We condemn this beastly attack and the terrorists who perpetrated it.
