Inform about time for swindle (5)
I believe the answer is:
sting
'swindle' is the definition.
(sting is a kind of swindle)
'inform about time' is the wordplay.
'inform' becomes 'sing' (I am not sure about this - if you are sure you should believe this answer much more).
'about' is an insertion indicator.
'time' becomes 't' (abbreviation).
'sing' enclosing 't' is 'STING'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for sting that I've seen before include "Bee's weapon" , "Entrapment operation; sharp pain" , "aka Gordon Sumner" , "fleece?" , "Sudden pain - swindle" .)
