The first is like saying 'goodbye' in portuguese, although they also say 'adeus' for longer goodbyes. The second is saying 'goodbye' in Italian, and of course they have a similar phrase in italian for longer goodbyes. Most of you will be familiar with the third. Chow in english is either something you feed your dog, something you do, or a name of a Chinese friend. So the similarities stick with the latin-based languages, but the germanic english is on its own. Oh english, you're so silly. You're the non-conformist of the european community. Thank goodness.
