To point misshapen ears out can be wiser (5)
I believe the answer is:
saner
'wiser' is the definition.
Both the answer and definition are comparative adjectives. Perhaps you can see a link between them that I can't see?
'to point misshapen ears out' is the wordplay.
'to point' becomes 'n' (North).
'misshapen' indicates an anagram.
'out' is an insertion indicator.
'ears' with letters rearranged gives 'saer'.
'n' going into 'saer' is 'SANER'.
'can be' acts as a link.
Can you help me to learn more?
(Other definitions for saner that I've seen before include "Less mad" , "less as hatter?" .)
