The IPA prefers terms "close" and "open" for vowels, and the name of the article follows this. However, a large number of linguists,[who?] perhaps a majority, prefer the terms "high" and "low".
Before the 1989 IPA Convention, the symbol for the close-mid back unrounded vowel was ⟨⟩, sometimes called "baby gamma", which has a flat top. The symbol was revised to be ⟨⟩, "ram's horns", with a rounded top, in order to differentiate it from the Latin gamma⟨ɣ⟩.Unicode provides only U+0264ɤlatin small letter rams horn (HTML ɤ), but in some fonts this character may appear as a "baby gamma" instead.
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 often they are in fact near-back.
It is unrounded, which means that the lips are not rounded.
