Way too many! receive (I got a new video game) feel (Sometimes I feel sad\ sometimes I get sad) understand (I get it. I don't get.) to contract a disease (I got sick last week.) Go to somewhere (I have to get to school before noon)

To me, "get" is one of those words you need to understand as a concept instead of a written definition. We understand the meaning of "get" based on the context. Adding to Prons' list, we could also add "achieve" (get first place), 'become" (get angry) and "arrive at" (get home). Probably a few more.
