The underscore [ _ ] (also called understrike, underbar, low line, underdash, underline, lower part of z or low dash) is a character that originally appeared on the typewriter and was primarily used to underline words. To produce an underlined word, the word was typed, the typewriter carriage was moved back to the beginning of the word, and the word was overtyped with the underscore character.
