Act to support those in need? (4,3)
I believe the answer is:
poor law
'act to support those in need?' is the definition.
I can't judge whether this definition defines the answer.
'act to support those in need?' is the wordplay.
'act' becomes 'law' (law is a kind of act).
'to support' means one lot of letters go next to another (in a down clue, some letters hold others up).
'those in need?' becomes 'poor' (the poor are needy people).
'law' after 'poor' is 'POOR-LAW'.
Can you help me to learn more?
(Other definitions for poor law that I've seen before include "provision for the needy once" , "Act to help penurious" , "welfare provision" .)
