Just remember, w and y are verbs in Welsh! That... might make it less intimidating, I dunno. (I'm not as sure about all the consonant clusters in Polish except that "sz" is sort of a "sh" sound. Slavic languages tend to be filled with a lot of sh and ch sounds, at least to my perception)

The Latin connection is really interesting. Usually I would expect to see more Germanic cognates in Scandinavian languages, but I'm probably talking out my butt about that.
