Dope is confusing a cent with financial support (10)
I believe the answer is:
assistance
'financial support' is the definition.
'assistance' can be an answer for 'support' (I've seen this before). I am unsure of the 'financial' bit.
'dope is confusing a cent' is the wordplay.
'dope' becomes 'ass'.
'confusing' indicates anagramming the letters.
'a'+'cent'='acent'
'acent' with letters rearranged gives 'tance'.
'ass'+'is'+'tance'='ASSISTANCE'
'with' is the link.
Can you help me to learn more?
(Other definitions for assistance that I've seen before include "Aid" , "Support" , "Help" .)
