Breve

A breve (/ˈbriːv/ ⓘ BREEV, less often /ˈbrɛv/ ⓘ BREV, neuter form of the Latin brevis "short, brief") is the diacritic mark ◌̆, shaped like the bottom half of a circle.

In many forms of Latin, ◌̆ is used for a shorter, softer variant of a vowel, such as "Ĭ", where the sound is nearly identical to the English /i/.

The traditional Cyrillic breve differs in shape and is thicker on the edges of the curve and thinner in the middle, as opposed to the Latin one,[1] but the Unicode encoding is the same.

In Emilian, ĕ ŏ are used to represent [ɛ, ɔ] in dialects where also long [ɛː, ɔː] occur.

In Esperanto, u with breve (ŭ) represents a non-syllabic u in diphthongs /u̯/, analogous to Belarusian ў.
