Stir things up in a possibly evil way (5)
I believe the answer is:
liven
'stir things up' is the definition.
I can't judge whether this defines the answer.
'possibly evil way' is the wordplay.
'possibly' is an anagram indicator.
'way' becomes 'n' (Compass direction - North).
'evil' with letters rearranged gives 'live'.
'live'+'n'='LIVEN'
'in a' is the link.
Can you help me to learn more?
(Other definitions for liven that I've seen before include "Cause excitement" , "Make (something) more interesting" , "Make animated" , "Animate, make energetic" , "Invigorate" .)
