The Somali Latin alphabet is an official writing script in the Federal Republic of Somalia and its constituent Federal Member States. It was developed by a number of leading scholars of Somali, including Musa Haji Ismail Galal, B. W. Andrzejewski and Shire Jama Ahmed specifically for transcribing the Somali language, and is based on the Latin script. The Somali Latin alphabet uses all letters of the English Latin alphabet except p, v and z. There are no diacritics or other special characters, although it includes three consonant digraphs: DH, KH and SH. Tone is not marked and a word-initial glottal stop is also not shown. Capital letters are used for names and at the beginning of a sentence.
