Run after cooking prune entree for businessman (12)
I believe the answer is:
entrepreneur
'for businessman' is the definition.
(I've seen this before)
'run after cooking prune entree' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'after' means one lot of letters go next to another.
'cooking' indicates an anagram (cook can mean to falsify or distort).
'prune'+'entree'='pruneentree'
'pruneentree' with letters rearranged gives 'entrepreneu'.
'r' put after 'entrepreneu' is 'ENTREPRENEUR'.
(Other definitions for entrepreneur that I've seen before include "impresario" , "Business risk-taker" , "Commercial figure" , "Business originator" , "Enterprising businessman" .)
