Anything helpful you can have recourse to (8)
I believe the answer is:
resource
'anything' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'helpful you can have recourse to' is the wordplay.
'recourse' anagrams to 'RESOURCE'.
Though, I'm not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for resource that I've seen before include "Provide with stock/assets" , "Ingenuity - expedient - supply" , "Means of help in project" , "Reserve supply that can be drawn upon when needed" , "Source of help" .)
