Rose's favourite boy? (5)
I believe the answer is:
petal
'rose's' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'favourite boy?' is the wordplay.
'favourite' becomes 'pet' (synonyms).
'boy?' becomes 'al' ().
'pet'+'al'='PETAL'
Can you help me to learn more?
(Other definitions for petal that I've seen before include "Leapt (anag.)" , "Floral feature" , "Flower part seen on plate" , "A bit of a bloomer" , "Bit of blooming" .)
