Jina lako ni nani?

Hello. Jina langu ni Beki. Jina lako ni nani? Nimefurahi kukutana na wewe. kukufahamu.

ku-fahumu = to understand, be acquainted 

I have read your other entries and know that you are more advanced now in your Swahili. So you probably already know that the infix "ku" means "you" and renders "na wewe" redundant and not needed.
