Ajami script

Ajami (Arabic: عجمي‎, ʿajamī) or Ajamiyya (Arabic: عجمية‎, ʿajamiyyah), which comes from the Arabic root for 'foreign' or 'stranger', is an Arabic-derived script used for writing African languages, particularly those of Songhai, Mandé, Hausa and Swahili, although many other African languages are written using the script, including Mooré, Pulaar, Wolof, and Yoruba. It is an adaptation of the Arabic script to write sounds not found in Standard Arabic. Rather than adding new letters, modifications usually consist of additional dots or lines added to pre-existing letters.
