Before the 1989 IPA Convention, the symbol for the close-mid back unrounded vowel was ⟨⟩, sometimes called "baby gamma", which has a flat top; this symbol was in turn derived from and replaced the inverted small capital A, ⟨Ɐ⟩, that represented the sound before the 1928 revision to the IPA. The symbol was ultimately revised to be ⟨⟩, "ram's horns", with a rounded top, in order to better 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 back in the mouth without creating a constriction that would be classified as a consonant. 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.
