The mid back unrounded vowel is a type of vowel sound, used in some spoken languages. While there is no dedicated symbol in the International Phonetic Alphabet that represents the "exact" mid back unrounded vowel between close-mid [ɤ] and open-mid [ʌ] (since no language is known to distinguish all three), 〈ɤ〉 is normally used. If precision is desired, diacritics can be used, such as 〈ɤ̞〉 or 〈ʌ̝〉.
Its vowel backness is back, which means the tongue is positioned as far back as possible in the mouth without creating a constriction that would be classified as a consonant. Note that unrounded back vowels tend to be centralized, which means that they're in fact near-back.
It is unrounded, which means that the lips are not rounded.
