Generous first and second violinists held whip round (6)
I believe the answer is:
lavish
'generous' is the definition.
(similar in meaning)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lavish that I've seen before include "Prodigal - unrestrained" , "Unstinting" , "Rich, elaborate" , "Plentiful, generous" , "shower" .)
