Prosecute criminal again for grabbing rights (7)
I believe the answer is:
arraign
'prosecute' is the definition.
(thesaurus)
'criminal again for grabbing rights' is the wordplay.
I cannot quite understand how this works, but
'rights' could be 'rr' (two abbreviations for right) and 'rr' is present in the answer.
an anagram of 'again' is 'aaign' which is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for arraign that I've seen before include "put on a charge" , "Act against" , "Indict, accuse" , "Accuse publicly" , "Call before court to answer criminal charge" .)
