 Swahili is now written in the Latin alphabet.There are a few digraphs for native sounds, "ch", "sh", "ng" and "ny"; "q" and "x" are not used, "c" is not used apart from unassimilated English loans and, occasionally, as a substitute for "k" in advertisements.There are also several digraphs for Arabic sounds, which many speakers outside of ethnic Swahili areas have trouble differentiating.
