I'm a little stuck... Click here to teach me more about this clue!

'of the ear' is the definition.
(I've seen this before)

'OTIC' is hidden within the letters.
However, I'm uncertain how this is indicated.

Can you help me to learn more?

(Other definitions for otic that I've seen before include "about hearing" , "relating to area incorporating canal" , "organ" , "of concern to the listener" , "Listener's" .)

I've seen this clue in the Sydney Morning Herald.
