Rich living: German's over for the first time (9)
I believe the answer is:
exuberant
'rich' is the definition.
(thesaurus)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for exuberant that I've seen before include "Abounding in vitality" , "Elated" , "High-spirited" , "full of glee" , "Vivacious; effusive" .)
