German cheers! (6)
I believe the answer is:
prosit
'german cheers' is the definition.
(German word used when raising a toast)
This is the entire clue.
(Other definitions for prosit that I've seen before include "Drinking call, good health to you" , "Happy days, perhaps" , "Drinking salutation" , "... [good-health]" , "good health is the answer" .)
