Use compulsion among the children for certain (7)
I believe the answer is:
enforce
'use compulsion among the children for certain' is the definition.
I can't judge whether this defines the answer.
'among the children for certain' is the wordplay.
'among' indicates a hidden word.
'ENFORCE' can be found hidden inside 'children for certain'.
Can you help me to learn more?
(Other definitions for enforce that I've seen before include "Implement - compel" , "Compel adherence to (a law)" , "exercise" , "Compel or impose obedience, say to law" , "Ensure observance of rules" .)
