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 neither the digit ⟨3⟩ nor Cyrillic small letter Ze, which arose from the Greek letter zeta, Ζ ζ), but a reversed Latinized variant of the lowercase epsilon, ɛ. The value was specified only in 1993; before that, it was transcribed ⟨ɛ̈⟩.
The IPA prefers terms "close" and "open" for vowels, and the name of the article follows this. However, a large number of linguists, perhaps a majority, prefer the terms "high" and "low".
Sulcalized (the tongue is grooved like in [ɹ]). 'Upper Crust RP' speakers pronounce a more open vowel [ɐː], but for most other speakers it's actually mid ([ɜ̝ː]). This vowel corresponds to rhotacized[ɝ] in rhotic dialects.
The most common realization of the vowel transcribed in IPA with ⟨ʌ⟩ in American English. Nevertheless, it is not a standard pronunciation throughout the whole country.[6][8]
