In the 1950s, a Sudanese Zaghawa schoolteacher named Adam Tajir created an alphabet for the Zaghawa language, sometimes known as the camel alphabet, deriving its glyphs from the clan brands used for camels and other livestock.He copied the inventory of the Arabic script, so the system was not ideal for Zaghawa.In 2000, a Zaghawa veterinarian named Siddick Adam Issa adapted Tajir's alphabet to a form which has proven popular in the Zaghawa community.Beria Giray Erfe is a full alphabet, with independent letters for vowels; however, diacritics are used to mark tone (grave accent for falling tone and acute accent for rising tone; high, mid, and low tone are unmarked), as well as advanced tongue root vowels (a macron derives /i e ə o u/ from the letters for /ɪ ɛ a ɔ ʊ/).There apparently is no letter for /ħ/, nor a distinction between /ɾ/ and /r/, both of which have been reported for Zaghawa.
