Found good person, cunning (5)
I believe the answer is:
start
'found' is the definition.
(as in to establish)
'good person cunning' is the wordplay.
'good person' becomes 'st' (saint).
'cunning' becomes 'art' (both can mean artfulness or trickery).
'st'+'art'='START'
(Other definitions for start that I've seen before include "Initiate" , "launch" , "Onset" , "Begin; flinch" , "Jump suddenly" .)
