Display centrepiece of sprightly PE on green (7)
I believe the answer is:
epergne
'display centrepiece' is the definition.
'epergne' can be an answer for 'centrepiece' (epergne is a kind of centrepiece). I'm unsure of the 'display' bit.
'sprightly pe on green' is the wordplay.
I cannot really see how this works, but
'pe' is found in the answer.
an anagram of 'green' is 'ergne' which is within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for epergne that I've seen before include "Table centrepiece with flowers, fruit" , "Large table centerpiece with branching holders" , "table display" , "Stand on table" , "Table ornament with small bowls on branched supports" .)
