Flowery piece (5)
I believe the answer is:
petal
'flowery piece' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'piece' is the wordplay.
I cannot quite understand how this works, but
'piece' could be 'p' (abbreviation for Pawn) and 'p' is found within the answer.
The remaining letters 'etal' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for petal that I've seen before include "part of seven [VIOLA]" , "Brightly-coloured part of flower" , "Small seal set in a ring" , "Floral segment" , "A bit of flower" .)
