Nouns can be formed from verbs using the suffixes -wI', which means one who does or thing which does, and -ghach, the nominalizer.
The suffix -wI' is similar to English -er in words like builder or toaster.
baHwI' - gunner (baH - fire (a torpedo) + -wI')
So'wI' - cloaking device (So' - cloak + -wI')
chenmoHwI' - builder (chenmoH - build + -wI')
These derived nouns are regular nouns and may be used to form compound nouns:
tIjwI'ghom - boarding party (tIjwI' - boarder + ghom - group)
tIjwI' - boarder (tIj - board + -wI')
When referring to inanimate things, -wI' usually means thing which does or thing which is used for:
joqwI' - thing which flutters (joq - flutter)
nanwI' - gouging tool (nan - gouge)
When referring to living beings, it means one who does or one who is:
po'wI' - one who is skilled (po' - be skilled)
pujwI' - one who is weak (puj - be weak)
TODO: Add something saying that nouns formed from verbs with -ghach also fall into the category of "Complex Nouns".
