Horn (diacritic)

The horn (dấu móc or dấu râu) is a diacritic mark attached to the top right corner of the letters o and u in the Vietnamese alphabet to give ơ and ư, unrounded variants of the vowel represented by the basic letter. In Vietnamese, they are rarely considered as diacritics; but rather, the characters ơ and ư are considered as different letters from o and u.
