Malagasy is written using the English alphabet, but without c, q, u, w and x. No accents or other diacritical marks are used. It was invented by David Jones as a replacement for Sorabe (a type of Arabic script). Most letters have their IPA values. However, y and i are both pronounced like /i/ and h is often silent. A few consonant digraphs (tr, dr, ts) are used.
