Noun
alphasyllabary (plural alphasyllabaries)
A segmental writing system in which consonant–vowel sequences are written as a unit: each unit is based on a consonant letter, and vowel notation is secondary; an abugida.
A third type, called abugida or alphasyllabary, is one where vowels are shown by diacritics or modifications of consonantal base letters, as in Devanagari and other South Asian scripts. Source: Internet
Formally, an alphasyllabary that is not an abugida can be converted to an abugida by adding a purely formal vowel sound that is never used and declaring that to be the inherent vowel of the letters representing consonants. Source: Internet
If all modifications are by diacritics and all diacritics follow the direction of the writing of the letters, then the abugida is not an alphasyllabary. Source: Internet
The formal definitions given by Daniels and Bright for abugida and alphasyllabary differ; some writing systems are abugidas but not alphasyllabaries, and some are alphasyllabaries but not abugidas. Source: Internet
Not every letter in the Latin alphabet is represented with one of those in the Baybayin alphasyllabary. Source: Internet
Phagspa is an example of an abugida that is not an alphasyllabary, and modern Lao is an example of an alphasyllabary that is not an abugida, for its vowels are always explicit. Source: Internet
