No twitching around the ears? (4)
I believe the answer is:
otic
'around the ears?' is the definition.
I can't tell whether this definition defines the answer.
'no twitching' is the wordplay.
'no' becomes 'O' (resembles 0 - 'no' can mean 'zero').
'twitching' becomes 'tic' (tic is a kind of twitching).
'o'+'tic'='OTIC'
Can you help me to learn more?
(Other definitions for otic that I've seen before include "Relating to ears" , "in relation to the listener" , "of concern to the listener" , "organ" , "of lugs" .)
