The syllable structure seems to be (C)(C)V(C)(C). Stress is almost always on the second-to-last syllable. When it isn’t, a schwa is usually involved. Stress can’t appear on ǝ, and, if there’s space, also can’t appear on the syllable before ǝ.

Writing System[]

The language uses an abugida called Izra.


Irathient is head-marking, uses VSO word order, 18 noun classes, Afrihili-inspired plurals, light verbs, inalienable possession, and a pertensive.

Number System[]

Irathient is one of the many languages that use a vigesimal, or base-20 number system.
