Nayanagari
Nayanagari is a conjunct free writing style for the Devanagari script. The Nayanagari alphabet set consists of only 8 vowels and 37 consonants. There are only a total of 45 characters in Nayanagari, and its use in computer and other applications are very simple and effective.
The Nayanagari vowels are always used in a progressive manner, while always being considered as a full independent alphabet. The Nayanagari consonants are all phonemic, as opposed to syllabic consonants of Devanagari, or of other Brahmi scripts.
