Brackets

brackets

A bracket (the half-moon shaped things on your keyboard) is a punctuation mark which is used in mathematics and in literature (language). Brackets are tall (high) punctuation (things like full stops) marks that are used in pairs (one, and then the other), sometimes to separate (break up) text (word). In the United States, "bracket" is usually talking about the "square" or "box" type. In British English, it usually means the "round" type, which is called a parenthesis in American English.
