A logical operator, also called a logical connective or a truth function, is a symbol or word used to connect two or more sentences, such that the sense of the compound sentence produced depends only on the original sentences.
The most common logical connectives are binary connectives which join two sentences which can be thought of as the function's operands. Also commonly, negation is considered to be a unary connective.
