Wrócić - to go back / come back / return / vomit

Fortunately, for wrócić to mean vomit it must be in context.  So you shouldn't need to be too careful when using this verb.  I will focus on the normal uses first then, perhaps, bring it up later on.

If you are forgetful you may need to go back for something.  Here we would use wróćić.
