This unit introduces the suffix -wI'.

It is added to verbs and produces nouns.

Similar to the English suffix -er, those nouns refer to a person who does that action or an item which does that action.

For example, from bom to sing, we get bomwI' singer (a person who sings) and from poSmoH to open we might make poSmoHwI' opener (a tool that opens things, or a person who opens things).

You have seen this suffix before as part of some nouns such as SuvwI', chungwI' or ghoqwI'.

A few nouns in -wI' have an unpredictable meaning, however, such as De'wI' computer; there is a noun De' data, information but no (known) verb De'.
