Hi Kit, here's a quick german lesson, but make sure you grab a phrase guide to help. Most europeans speak better english than our german, BTW. I usually start out a bit formal, but have found the Germans, Swiss, and Austrians love it when you try a few simple phrases:
Guten morgen (pronounce Gooten) --FOrmal GOod morning greeting;
Guten Tag (gooten tahg)-- Formal good day greeting or departing;
Gute Nacht-- Formal good night;
or near NE Switzerland/Austria: Gruss Gott (God is great)-- Good day/Hello;
Aufwiedersehen--)oufveedersahn) a semi formal goodbye
Another one: Sehr Schoen (sahr shern)-- very beautiful-- which works for scenery or people!
Informally: Tag (tahg) mean "hi"
Tchuss (chooss): informal good bye
or one that will get a smile from just about everyone: Ausgetzeitnet! (ousgetzightnet)-- means roughly "Superb outstanding and wonderful"-- all rolled into one. Tough to pronounce, but they'll crack up anyway!
Prosit!
