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⟩. Note that the IPA symbol is not the digit ⟨3⟩, but a reversed epsilon.

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", and these are the only terms found in introductory textbooks on phonetics such as those by Peter Ladefoged.

Features

• Its vowel height is open-mid, also known as low-mid, which means the tongue is positioned halfway between an open vowel (a low vowel) and a mid vowel.
• Its vowel backness is central, which means the tongue is positioned halfway between a front vowel and a back vowel.
• Its vowel roundedness is unrounded, which means that the lips are not rounded.
• In non-rhotic varieties of English, it is sulcalized, which means the tongue is grooved as in an English [ɹ].
