Oa is a language created by Edgar Grunewald for his YouTube channel Artifexian. It is based on Korea's Hangul (한글) writing system.
Artifexian could not pronounce trilled /r/. He has since learned how to.
|Diphthongs||ai, ia, oi, io, oa, ao|
Oa's fundamental syllable structure is (C)(C)V(C)(C).
Oa ommits coda ʍ, ʙ, ʀ, h, and j
Oa ommits the glottal stop and ʍ in consonant clusters
Oa clusters usually follow o+s in onset and s+o for coda
These glyphs are part of a featural system and are based on the several sounds of Oa.
In this language, there is no future tense.
The numbers and their words are explained in this video.
