2. (IPA, rare) A diacritic added to a vowel letter with a descender (i.e. ⟨y⟩) to show that it is nonsyllabic.

3. (UPA) a central vowel.

(UPA): With normal vowels, the breve appears below the letter, e.g. ⟨i̮ e̮ ɛ̮ a̮⟩ and rounded ⟨u̮ o̮ ɔ̮ ɑ̮⟩. However, when the vowel letter is rotated to indicate a reduced vowel, the breve is rotated as well: ⟨ᴉ̑ ə̑ ᴈ̑ ɐ̑ ɒ̑⟩.^[1]
