Today’s word is a verbal suffix. It is used in place of a full verb. The suffix is: -opka. The suffix -opka can take the place of the verb sanauli. It expresses ” want” as it is the “Desiderative” of Klamath. This just means that it expresses the idea of desiring-or wanting-whatever the verb action is.
gena + -opka=genopka=desire or want to go.
at ni sanauli gena. I want to go. OR
at ni genopka. I want to go.
There is no difference in meaning. The speaker is just making a choice of how to say something.
Several days ago, we had the verb made from the noun iwam + -la=iwamla=gather huckleberries.
You could say:
gen waytas ni sanauli gena iwamla. Today I want to go gather huckleberries.
OR You could say: gen waytas ni genopka iwamla. Today I want to go gather huckleberries.
The two sentences have the same information. There is no difference in meaning.
