For actual letters, typed or handwritten, I still use "Dear" to address and "Sincerely" or "Yours truly" to sign off. For emails I address by title and last name when its formal, and sign off with "Respectfully". I haven't written an informal letter in a long time since I don't know anyone who actually still wants to see my handwriting (and I'm not typing a letter on the computer). Informal email is addressed with "Hello", "Hi" or some other form of informal salutation and signed off with "ciao", "bye", "love" or my favorite "szia" (as much as bye in Hungarian - and no, I don't speak it).

While this is a discussion of Latin words in English, I'm frightened by the inclusion of a German word, Schnapps, the plural of which is not Schnappsen. Until reading this discussion, I have never seen Schnappsen anywhere (not that I'm a regular consumer of such beverages). Also Schnapps, though directly taken from German is spelled with only one 'p' in its original form. The plural in German would be Schnaepse (if you can't make the umlaut), or Schnäpse. Beyond that forums vice fora is a matter of preference though my spell check prefers the former, I the latter.
