Yi script
Languages that use syllabaries today tend to have simple phonotactics, with a predominance of monomoraic (CV) syllables. For example, the modern Yi script is used to write languages that have no diphthongs or syllable codas; unusually among syllabaries, there is a separate glyph for every consonant-vowel-tone combination (CVT) in the language (apart from one tone which is indicated with a diacritic).
