After quiz, family you could turn to late in the day? (7)
I believe the answer is:
pumpkin
'could turn to late in the day?' is the definition.
I can't tell whether this definition defines the answer.
'after quiz family' is the wordplay.
'after' says to put letters next to each other.
'quiz' becomes 'pump' (both can mean to interrogate).
'family' becomes 'kin' (synonyms).
'pump' next to 'kin' is 'PUMPKIN'.
'you' is the link.
Can you help me to learn more?
(Other definitions for pumpkin that I've seen before include "Big squash" , "Huge yellowy fruit" , "Hallowe'en fruit" , "It's a Halloween tradition" , "big, yellow, and round" .)
