Exact child no longer accepting element of education? (6)
I believe the answer is:
extort
'exact' is the definition.
(thesaurus)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for extort that I've seen before include "Squeeze" , "Obtain by force or intimidation" , "Force to fork out" , "Blackmail" , "Force from, tax or confession" .)
