Notice round about the ears (4)
I believe the answer is:
otic
'notice round about the ears' is the definition.
I can't judge whether this defines the answer.
'notice round about' is the wordplay.
'about' indicates the answer is hidden within the clue (the clue goes around or about the answer).
'OTIC' is hidden within 'notice round'.
Can you help me to learn more?
(Other definitions for otic that I've seen before include "relating to area incorporating canal" , "Relating to ears" , "of concern to the listener" , "of lugs" , "Listener's" .)
