Latin alpha

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

The letter Latin alpha with a script-a shape, as in the International phonetic alphabet

The lowercase letter A: the double-story lowercase on the left; the single-story lowercase, also called literacy a or script-a, on the right. The latter can be confused with the Latin alpha.

Latin alpha (majuscule: Ɑ, minuscule: ɑ) or script a is a letter of the Latin alphabet, based on one lowercase form of a, or on the Greek lowercase alpha (α). Although ⟨ɑ⟩ is normally just an allograph of ⟨a⟩, there are instances in which the two letters must be carefully 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:
  • Fe'fe'
  • Mbembe
  • Mbo (?): but not Akoose, though it does have phonemes /aa/ and /ɑɑ/; nor Bakaka.
  • 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.

In Cameroon languages, ⟨Ɑ ɑ⟩ must look like the classical lowercase Greek alpha to better differentiate it from the letter a in script form.
