Terrible rage after child makes accusation (6)
I believe the answer is:
charge
'accusation' is the definition.
(thesaurus)
'terrible rage after child' is the wordplay.
'terrible' indicates anagramming the letters.
'after' says to put letters next to each other.
'child' becomes 'ch'.
'rage' is an anagram of 'arge'.
'arge' put after 'ch' is 'CHARGE'.
'makes' acts as a link.
(Other definitions for charge that I've seen before include "Accusation (in court)" , "Keeping" , "The price asked for goods or services" , "Move quickly and violently" , "Formally accuse (someone)" .)
