Support for those who can't afford to take action (5,3)
I believe the answer is:
legal aid
'support for those who can't afford to take action' is the definition.
The definition suggests a singular noun which matches the answer.
'support for those' is the wordplay.
'support' becomes 'aid' (to aid is to help or support).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'those' becomes 'legal' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'aid' after 'legal' is 'LEGAL AID'.
Can you help me to learn more?
(Other definitions for legal aid that I've seen before include "Funding for poor litigants" , "Financial help for defence in court" , "Money for poor litigant" , "Public help for litigant" , "help with case" .)
