Tease us about making money (5)
I believe the answer is:
sugar
'money' is the definition.
(informal term for money)
'tease us about' is the wordplay.
'tease' becomes 'rag' ('rag' can be a synonym of 'tease').
'about' shows that the letters should be reversed in order.
'rag'+'us'='ragus'
'ragus' back-to-front is 'SUGAR'.
'making' acts as a link.
(Other definitions for sugar that I've seen before include "Argus (anag.)" , "rotter!" , "flattery" , "White crystalline sweetener" , "Sweet white substance" .)
