Translation of waive in German

My parents were Italian, but the first language I learned was Spanish, since we lived in southern Spain. Very close to Gibraltar. When I was older, like twelve I moved with them back to Lucca in Italy.
I do translate to Spanish, but I always inform the client about my problem, in order not to have any dispute. The corrections I receive after proof reading are mostly a confusion between the different time forms in Spanish.
I've never been to Switzerland, but I'd like to go to the Alps. Until now I was only in Austria and in France. Maybe I will go there, for example skiing in Davos or in another nice mountain village.
