Anything helpful you can have recourse to (8)
I believe the answer is:
resource
'anything' is the definition.
Both the answer and definition are singular nouns.
Perhaps there's an association between them I don't understand?
'helpful you can have recourse to' is the wordplay.
'recourse' anagrams to 'RESOURCE'.
Though, I am not clear 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" .)
