Ask family insistently for Halloween requirement (7)
I believe the answer is:
pumpkin
'insistently for halloween requirement' is the definition.
I can't judge whether this defines the answer.
'ask family' is the wordplay.
'ask' becomes 'pump' (I can't justify this - if you can you should give a lot more credence to this answer).
'family' becomes 'kin' (synonyms).
'pump'+'kin'='PUMPKIN'
Can you help me to learn more?
(Other definitions for pumpkin that I've seen before include "Large type of gourd" , "Type of squash" , "Big squash" , "coach would appear at midnight" , "Large orange fruit of the squash family" .)
