Other forms: greasier; greasiest

Greasy things are oily and slick, like those delicious greasy fries you eat at the state fair, and the greasy fingers you lick clean.

Anything that contains or is covered with slippery fat is greasy, whether it's fried dough or a car's engine. Things that look oily, like your brother's unwashed hair, are also greasy. Both grease and greasy come from a Latin root meaning "fat." A "greasy spoon" is a small, inexpensive restaurant or diner, named for the fact that many foods in such a place tend to be fried in oil or other fats.
