Here are some helpful (and likeable!) phrases that we found in Germany!

Sprecken see English? (Do you speak English?)
Isch Sprecken Kein Deustch. (I do not speak any German ~> very helpful when people start talking to you in German and you have no idea what they’re saying)
Entrue-D-gong (Excuse me, both to get people’s attention and to say sorry, pardon me, etc)
Bitte (We think this may mean several things: You’re welcome, please, go ahead, pardon me, and sorry? (ie, when you can’t understand what the person said and are asking them to repeat.) )
