Floral plate design (5)
I believe the answer is:
petal
'floral plate design' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'plate design' is the wordplay.
'design' indicates an anagram.
'plate' with letters rearranged gives 'PETAL'.
Can you help me to learn more?
(Other definitions for petal that I've seen before include "part taken from stock?" , "Flower part seen on plate" , "Corolla leaf" , "Leapt (anag.)" , "Part of a plant's perianth that is usually brightly coloured" .)
