The open-mid central unrounded vowel, or low-mid central unrounded vowel, is a type of vowel sound, used in some spokenlanguages. 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 (з). 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⟩.
Sulcalized (the tongue is grooved like in [ɹ]). "Upper Crust RP" speakers pronounce a more open vowel [ɐː], but for most other speakers it is actually mid ([ɜ̝ː]). This vowel corresponds to rhotacized[ɝ] in rhotic dialects.
