Stir up evil, perhaps, on the way (5)
I believe the answer is:
liven
'stir up' is the definition.
(thesaurus)
'evil perhaps on the way' is the wordplay.
'perhaps' indicates an anagram.
'on' means one lot of letters go next to another.
'the way' becomes 'n' (Compass direction - North).
'evil' anagrammed gives 'live'.
'live'+'n'='LIVEN'
(Other definitions for liven that I've seen before include "Animate, make energetic" , "Vitalise" , "Spice up" , "Make animated" , "Make (something) more interesting" .)
