Tilde

The tilde (~) is a grapheme which has several uses, described below. The name of the character comes from Spanish, from the Latin titulus meaning a title or superscription, and is pronounced "TILL-duh" (IPA ) or "TILL-day". It was originally written over a letter as a diacritic (see below), but has since acquired a number of other uses as a character in its own right. In this capacity (especially in lexicography) it is also sometimes known as the swung dash (usually lengthened to ?).
