ⓘ Open-mid central unrounded vowel

The open-mid central unrounded vowel, or low-mid central unrounded vowel, is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ ɜ ⟩. The IPA symbol is not the digit ⟨3⟩ or the Cyrillic small letter Ze. The symbol is instead a reversed Latinized variant of the lowercase epsilon, ɛ. The value was specified only in 1993, until then, it had been transcribed ⟨ ɛ̈ ⟩.

In ⟨"ɜ"⟩ letter can be used with the raising diacritic, ⟨"ɜ"⟩ to denote the mid Central unrounded vowel. It can also be used with a lowering diacritic ⟨"ɜ"⟩ to denote a near-open unrounded vowel.

Conversely, ⟨ ə ⟩ in the mid-Central vowel may be used during the lowering diacritic ⟨ ə ⟩ to indicate open-mid Central unrounded vowel, although it is more accurately written with additional diacritical unrounding ⟨ ə ⟩ to explicitly denote the lack of rounding the canonical value for the MPA ⟨ ə ⟩ is undefined for rounding.
