The tilde (/ˈtɪldə/, /ˈtɪldi/; ˜ or ~; also referred to informally as squiggly or squiggle(s)) is a grapheme with several uses. The name of the character comes from Portuguese and Spanish, from the Latin titulus meaning "title" or "superscription", though the term "tilde" has evolved and now has a different meaning in linguistics. Some may refer to it as a "flourish".
