Assistance, support (7)
I believe the answer is:
succour
This clue is a double definition.
'assistance' is the first definition.
(I know that succour is a type of assistance)
'support' is the second definition.
(I know that succour is a more specific form of the action aid)
(Other definitions for succour that I've seen before include "Comfort" , "Help given in time of need" , "Encourage" , "Render assistance to" , "Assistance, support" .)
