Why not to cook and to learn?
It can be. It’s the context that would matter.
Kupika is to cook and mpishi is a cook
Are Kupika and Mpishi related words, or is the similarity just a happy coincidence?
They are related.
Can you explain the relations between the words kupika na mpishi?
Not sure how k became sh, but ku- marks infinitives and m- generally marks people. So mpishi is a person that cooks and kupika is the action "to cook".
is anyone good at this one
oooooooooh
