Plate shaped like a bit of blossom (5)
I believe the answer is:
petal
'a bit of blossom' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'plate shaped' is the wordplay.
'shaped' indicates anagramming the letters.
'plate' anagrammed gives 'PETAL'.
'like' acts as a link.
Can you help me to learn more?
(Other definitions for petal that I've seen before include "Bloom's part" , "A bit of flower" , "Plate (anag.)" , "Coloured segment of flower" , "Leaf-like part of flower head" .)
