An important verb, found only in the imperative form

"kla" means "to eat," but one only needs to know the form "kul!" which means "eat!"
My host parents (especially mother) say "kul!" to me a lot, regardless of how much I may be eating at the time they're telling me to eat. I have been told (insistently!) to eat while currently chewing on large amounts of food.
The following is quickly becoming a common event:
I am eating food, possibly a borderline-rudely large amount of food. The mother looks at me, says "kul! kul!" and the dad then says "kul!". My mouth is full of food so I can't really say anything, I just kind of nod and chew a little faster. Then the dad puts more food on my plate, regardless of how much I've already eaten. Then he says "kul!"

Another example of this is the first night I was here, when they were serving us tea. They served me one cup of tea, which I gladly drank. Then they served me another while I wasn't looking, which I also gladly drank (the tea is really quite amazing). Then the mother asked me if I wanted more, to which I said "la shukrun" (no thanks). She insisted, and I said again, "la shukrun, la shukrun," to which she said "un petit peu!" and then filled up my cup all the way.
