I have an extremely basic knowledge of linguistics/philology. Enough to sound educated while knowing very little of real value.
But yeah, I know some curse words in Danish and Scandinavian phrases as they relate to literature.
For future reference, I know enough Spanish and German to take care of the essentials if I'm ever lost in a country with either of those as an official language. Currently, I'm trying to gain a similar level of knowledge in French and having an extremely tough time doing it.
