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 there's a link between them I don't understand?
'to point misshapen ears out' is the wordplay.
'to point' becomes 'n' (North).
'misshapen' indicates anagramming the letters.
'out' is an insertion indicator.
'ears' anagrammed gives 'saer'.
'n' placed inside '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?" .)
