In Vietnamese, a tilde over a vowel represents a dipping tone ( ngГЈ).

Current languages in which the tilded вџЁnвџ© (вџЁГ±вџ©) is used for the palatal nasal consonant /ЙІ/ include: In addition, the word tilde can refer to any diacritic in this language for example, the acute accent in JosГ© is also called a tilde in Spanish. In this language, вџЁГ±вџ© is considered a separate letter called eГ±e ( IPA: ), rather than a letter-diacritic combination it is placed in Spanish dictionaries between the letters вџЁnвџ© and вџЁoвџ©. The tilded вџЁnвџ© (вџЁГ±вџ©, вџЁГ‘вџ©) developed from the digraph вџЁnnвџ© in Spanish. For example вџЁanвџ© gives the pronunciation whereas вџЁaГ±вџ© gives. In Breton, the symbol вџЁГ±вџ© after a vowel means that the letter вџЁnвџ© serves only to give the vowel a nasalised pronunciation, without being itself pronounced, as it normally is. For example, is the transcription of the pronunciation of the word 'Lyon' in French (inherited from Portuguese as well).

Current languages and alphabets in which the tilde is used as a sign of nasalization include: It indicates nasalization of the base vowel: mГЈo 'hand', from Lat. It is also as a small вџЁnвџ© that the tilde originated when written above another letters, marking a Latin вџЁnвџ© which had been elided in old Galician-Portuguese. The tilde was also used occasionally to make other abbreviations, such as over the letter вџЁqвџ© (' qМѓ') to signify the word que ('that'). It was also used in Portuguese, Catalan and Spanish. (Compare the development of the umlaut as an abbreviation of вџЁeвџ©.) The practice of using the tilde over a vowel to indicate omission of an вџЁnвџ© or вџЁmвџ© continued in printed books in French as a means of reducing text length until the 17th century. When an вџЁnвџ© or вџЁmвџ© followed a vowel, it was often omitted, and a tilde (i.e., a small вџЁnвџ©) was placed over the preceding vowel to indicate the missing letter this is the origin of the use of tilde to indicate nasalization. Later, it was used to make abbreviations in medieval Latin documents.

It was first used in the polytonic orthography of Ancient Greek, as a variant of the circumflex, representing a rise in pitch followed by a return to standard pitch. In some languages, the tilde is used as a diacritical mark ( ЛњвЂ‰) placed over a letter to indicate a change in pronunciation, such as nasalization. Another approximation symbol is в‰€, meaning 'approximately equal to.' Diacritical use It can mean 'similar to', including 'of the same order of magnitude as', such as 'x ~ y' meaning that x and y are of the same order of magnitude. This symbol (in English) sometimes means 'approximately', such as '~30 minutes ago' meaning 'approximately 30 minutes ago'. 4.2.1 Unicode and Shift JIS encoding of wave dash.Especially in lexicography the tilde as a separate character or swung dash ( вЃ“) is used in dictionaries to indicate the omission of the entry word. And there are additional similar characters for different roles. These are encoded in Unicode at U+0303 в—ЊМѓ combining tilde and U+007E ~ tilde (as a spacing character). It was originally written over a letter as a mark of abbreviation, but has since acquired a number of other uses as a diacritic mark or a character in its own right. 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.
