Ga was first written in about 1764, by
Christian Jacob Protten (1715–1769), who was the son of a Danish soldier and a Ga woman. Protten was a
Gold Coast Euro-African Moravian missionary and educator in the eighteenth century. In the mid-1800s, the Germany missionary
Johannes Zimmermann (1825–1876), assisted by the Gold Coast historian
Carl Christian Reindorf (1834–1917) and others, worked extensively on the grammar of the language, published a dictionary and translated the entire Bible into the Ga language. The orthography has been revised a number of times since 1968, with the most recent review in 1990. The writing system is a
Latin-based
alphabet and has 26 letters. It has three additional letter symbols which correspond to the
IPA symbols. There are also eleven digraphs and two trigraphs. Vowel length is represented by doubling or tripling the vowel symbol, e.g. 'a', 'aa' and 'aaa'. Tones are not represented. Nasalisation is represented after
oral consonants where it distinguishes between
minimal pairs. The Ga alphabet is: Aa, Bb, Dd, Ee, Ɛɛ, Ff, Gg, Hh, Ii, Jj, Kk, Ll, Mm, Nn, Ŋŋ, Oo, Ɔɔ, Pp, Rr, Ss, Tt, Uu, Vv, Ww, Yy, Zz The following letters represent sounds which do not correspond with the same letter as the
IPA symbol (e.g. B represents ): • J j - • Y y - Digraphs and trigraphs: • Gb gb - • Gw gw - • Hw hw - • Jw jw - • Kp kp - • Kw kw - • Ny ny - • Ŋm ŋm - • Ŋw ŋw - (an allophone rather than a phoneme) • Sh sh - • Ts ts - • Shw shw - • Tsw tsw - ==Oral literature==
