It's dope? Somehow get payment (7)
I believe the answer is:
deposit
'payment' is the definition.
(I know that deposit is a type of payment)
'it's dope? somehow' is the wordplay.
'somehow' is an anagram indicator.
'its'+'dope'='itsdope'
'itsdope' anagrammed gives 'DEPOSIT'.
'get' acts as a link.
(Other definitions for deposit that I've seen before include "Sum of money paid into a bank account" , "is one back on the bottle?" , "Plant" , "Lodge money in bank account" , "Drop" .)
