Beyond the definition

The word "double" seems simple at first. Most often, it means two or twice as much—like a double scoop of ice cream or a double feature at the movies, where you get two films. But "double" can be used in a few different ways.

It can describe something with two parts, like a double door or a double-breasted coat. It can also mean to make something twice as much: "If you double the recipe, you'll have enough cookies for everyone." Sometimes, a "double" is a person who takes someone else's place or looks very similar, such as a stunt double in a movie. So when you hear "double," think about whether it means amount, shape, or a copy of someone or something.
