Question relatives about vegetable production (7)
I believe the answer is:
pumpkin
'vegetable production' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'question relatives' is the wordplay.
'question' becomes 'pump' (pumping is a kind of questioning).
'relatives' becomes 'kin' (I've seen this in another clue).
'pump'+'kin'='PUMPKIN'
'about' is the link.
Can you help me to learn more?
(Other definitions for pumpkin that I've seen before include "coach would appear at midnight" , "Orange-yellow fruit" , "Large type of gourd" , "Type of squash" , "Large fruit with many seeds" .)
