Gets Holly back into shape by cutting back on the Chardonnay? (6)
I believe the answer is:
pruner
'back on the chardonnay?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for pruner that I've seen before include "He reduces growth" , "One cutting off" , "Clipper" , "One trimming shrub" .)
