A cry of approval (4)
I believe the answer is:
'cry of approval' is the definition.
Although both the answer and definition are verbs in their base form, I cannot understand how one could define the other.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hear that I've seen before include "to judge" , "Perceive aurally" , "receive information" , "Get wind of" , "Catch" .)
