Somali Latin alphabet
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".

Capital letters are used for names and at the beginning of a sentence. Form. The Somali Latin alphabet is largely phonemic, with consonants having a one-to-one correspondence between graphemes and phonemes. Long vowels are written by doubling the vowel. However, the distinction between tense and lax vowels is not represented. Diphthongs are represented using Y or W as the second element (AY, AW, EY, OY and OW) and long diphthongs are shown with the first vowel doubled. As there is no central regulation of the language, there is some  variation in orthography, the endings -ay and -ey being particularly interchangeable.
