Klingon forms nouns from verbs using the suffixes -wI', which means one who does or thing which does, and -ghach, the nominializer.

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".
