German has a word for Mr. and Mrs. but not Ms (Miss). Frau is used as Mrs, and I guess in place of the non-existent Me. Frau also means woman, and wife, so I guess how you use Frau depends on the context. But also the book gave an imteresting little tid bit about how the word Fräulein use to be the word for Miss (Ms), but it is no longer used.
