The '''tilde''' is a variable-use diacritic.
The first use of tilde, ◌͂, was in Ancient Greek, though in that context it's called circumflex. This diacritic was used for indicating pitch accent.<ref name=greek_tilde>[[Wikipedia:Tilde#Pitch|Tilde, Pitch]] at Wikipedia.</ref> In medieval times scribes used tildes above letters to indicate omissions. It could stand for an omitted Mm or Nn, though it could also stand for whole sequences of letters. Ññ comes from a digraph, Nn nn, as the tilde is essentially the same as a small Nn. Vowels with tilde in Portuguese have a similar origin.<ref name=tilde_origins>[[Wikipedia:Tilde|Tilde]] at Wikipedia.</ref>


Unicode recognizes the following precomposed tilde-appended letters: ''ã ẽ ĩ ɫ ñ õ ũ ṽ ỹ''

The first use of tilde, ◌͂, was in Ancient Greek, though in that context it's called circumflex. This diacritic was used for indicating pitch accent.[1] In medieval times scribes used tildes above letters to indicate omissions. It could stand for an omitted Mm or Nn, though it could also stand for whole sequences of letters. Ññ comes from a digraph, Nn nn, as the tilde is essentially the same as a small Nn. Vowels with tilde in Portuguese have a similar origin.[2]
