Telugu is a phonetic language, written from left to right, with each character representing generally a syllable. There are 52 letters in the Telugu alphabet: 16 Achchulu which denote basic vowel sounds, 36 Hallulu which represent consonants. In addition to these 52 letters, there are several semi-vowel symbols, called Maatralu, which are used in conjunction with Hallulu and, half consonants, called Voththulu, to form clusters of consonants.
