abugida
Let an agent explain what an abugida is and how it differs from other writing system types, identify abugidas and their families, relay how vowels and conjuncts are handled, and point to standards for encoding and typography.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain what an abugida is and how it differs from other writing system types, identify abugidas and their families, relay how vowels and conjuncts are handled, and point to standards for encoding and typography.
A writing system in which each basic symbol represents a consonant with an inherent vowel, and other vowels are marked by diacritics or modifications of the consonant sign, as in the Brahmic scripts of South and Southeast Asia such as Devanagari, Malayalam and Assamese, the Ethiopic script, Canadian Aboriginal syllabics, Thaana and the Pollard Miao script; the term was proposed by Peter Daniels to distinguish these systems from alphabets, abjads and syllabaries.
What it is for: Writing languages with consonant-vowel signs.
It can be explain the type and its features; identify abugidas and families; explain vowel and conjunct handling; relay encoding standards.
Distinguishing features
Inherent vowel
Vowel diacritics
Consonant clusters by conjuncts or vowel killers
Typologically between abjad and syllabary
What it looks like
Scripts with base consonant signs modified by attached marks above, below or beside them.
Physical character
term coined: 1990 year - Peter Daniels
How it is recognised
Consonant signs with inherent vowel and vowel marks
Brahmic, Ethiopic, syllabics and others
Abjads omit vowels; alphabets write vowels as separate letters; syllabaries have distinct signs per syllable

What the second pass must settle

- How should Unicode standards be linked?
- The registry entry has merged aliases naming specific scripts; should they be split off?
