Hare around, we learn (4)

I believe the answer is:

hear

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

'learn' is the definition.
(I know that learn can be written as hear)

'hare around we' is the wordplay.
'hare' anagrams to 'HEAR'.
But, I am not sure how this is indicated.

Can you help me to learn more?

(Other definitions for hear that I've seen before include "Catch" , "Perceive aurally" , "Perceive sound" , "Pick up, aurally" , "Perceive audibly" .)

I've seen this clue in the Evening Standard.
