this script looks closest to a
syllabary; like hiragana, katakana, or cherokee.
though if those are the sounds each one make, that is pretty limited imo
what you should do instead, is to first make a table of consonants and vowels, and fill in most of them with glyphs. you can either have all filled in, and/or have a few missing, or have some weird ones that dont make sense (like how japanese suddenly has tsu in its t series).
you should therefore learn a little on how the
IPA works.
at this moment
these videos will help on this section of the language; phonology, and they also explain the IPA.other videos on grammar and syntax are expected to be uploaded.
absolutely do not limit the number of glyphs based on the number of english letters.
if you need any help with the grammar/syntax i can help
