Provoke mimic pinching last of profit (9)
'provoke' is the definition.
(stimulating is a kind of provoking)
'mimic pinching last of profit' is the wordplay.
'mimic' becomes 'simulate' (I've seen this before**).
'pinching' is an insertion indicator (taking inside).
'last of' suggests the final letters.
The final letter of 'profit' is 't'.
'simulate' enclosing 't' is 'STIMULATE'.
(Other definitions for stimulate that I've seen before include "Encourage" , "Excite the feelings of" , "Mutilates so as to make more active" , "Incite to action" , "Kindle?" .)
But I've got no explanation for this one! Could you help me understand?
