Colon (letter)

Other languages include Hupa of California, Oʼodham of Arizona, Sayula Popoluca of Mexico and Mohawk of Ontario.

The colon is used as a grammatical tone letter in Budu in the Democratic Republic of the Congo, in Sabaot in Kenya, and in some Grebo in Liberia.

It is used for the vowels /ɛ/ and /ɔ/ in several languages of Papua New Guinea: Erima, Gizra, Go꞉bosi, Gwahatike, Kaluli, Kamula, Kasua, Kuni-Boazi and Zimakani.

In the International Phonetic Alphabet, a special triangular colon-like letter is used to indicate that the preceding consonant or vowel is long.

If the upper triangle is used without the lower one (U+02D1 ˑ MODIFIER LETTER HALF TRIANGULAR COLON), it designates a half-long vowel or consonant.
