Ben (I) --> Bana (to me) (dative case)
Sen (You) --> Sana (to you) (dative case)
Vermek = To give
If you use only root of the verb, then you get the imperative form in terms of "You do!"
Ver = Give
So, since "sana" word's subject and "ver" imperative's reference are the same, it is a little absurd. " Give you!"
Bana ver = Give me!
