Ridicule the people here about money (5)
I believe the answer is:
sugar
'money' is the definition.
(informal term for money)
'ridicule the people here about' is the wordplay.
'ridicule' becomes 'rag' (both can mean to tease).
'the people here' becomes 'us' (I can't justify this - if you can you should believe this answer much more).
'about' shows that the letters should be reversed in order.
'rag'+'us'='ragus'
'ragus' backwards is 'SUGAR'.
Can you help me to learn more?
(Other definitions for sugar that I've seen before include "Basic sweetener" , "Sweetening agent" , "Sweeten" , "--- Ray Robinson, boxer" , "Term of affection" .)
