How to Present a Verb?

After looking at all the different tenses and moods one might justly ask, how then do I enunciate a verb in Kareyku? Or what's the equivalent to an infinitive/gerund in Kareyku? As it happens, there is such a form. In Kareyku the intransitive form in the third person is used to convey what other languages do by way of the infinitive or a noun gerund form.

qappalta, to eat/the eating

tokilta, to defend/the defending

Or to make a sentence;

qappalta pile gade, "eating fish is good"

So in this case it's a general statement that eating fish is something good or healthy. It can also be used as purpose constructions such as English "to eat", example:

marinma tokilta odanu inwa, "come to defend your son"
