Thread: Поговорить и Разговорить

Medved (Е), that's the right direction.

There is also another specific meaning. And the Eng. verb 'chat up' is used for it.

Chat up – To chat someone up is to try and pick them up. If you spotted a scrummy girly in a bar you might try to chat her up. Or a girl might try and chat up a chap!

So sometimes разговорить may be used for such a situation. I am not sure this is the exact equivalent, but it makes sense to compare разговорить and 'chat up'.

I guess chat up is more like "заговорить" или "уболтать"
