The letter Latin alpha with a lowercase Greek alpha shape, as in the African reference alphabet or the General Alphabet of Cameroon Languages

Usage

Although |ɑ| is normally just an allograph of ⟨a⟩, there are instances in which the two letters are distinguished:

• In the International Phonetic Alphabet, ⟨ɑ⟩ represents an open back unrounded vowel, while ⟨a⟩ represents an open front unrounded vowel. It has the shape of a script-a.
• Also in the General Alphabet of Cameroon Languages, ⟨Ɑ ɑ⟩ usually represents an open back unrounded vowel, while ⟨A a⟩ represents an open front unrounded vowel. The former is used in the orthographies of several languages of Cameroon, including:
  • Feʼfeʼ^[1][2]
  • Mbembe^[3]
  • Mbo (?): but not Akoose, though it does have phonemes /aa/ and /ɑɑ/;^[4] nor Bakaka.^[5]
  • in some languages, the script-a form (also called literacy form) of the letter ⟨A a⟩, with the lowercase much like the IPA ⟨ɑ⟩, is used and should not be confused with the Latin alpha ⟨Ɑ ɑ⟩ of the GACL; for example, in Muyang, the literacy ⟨A a⟩ represents an open-mid central unrounded vowel but it is not ⟨Ɑ ɑ⟩; the Latin alpha is not used.^[6]
• In typography, it is sometimes referred to as the single-story a, to distinguish it from double-story a.

In Cameroon languages, lowercase ⟨ɑ⟩ is typeset as a lowercase Greek alpha to better differentiate it from the letter a in script or italic form. the capital is typically typeset as a large Latin script a.
