To rush can make you hear amiss (4)
I believe the answer is:
hare
'to rush can make you' is the definition.
I can't judge whether this defines the answer.
'hear amiss' is the wordplay.
'amiss' is an anagram indicator.
'hear' is an anagram of 'HARE'.
Can you help me to learn more?
(Other definitions for hare that I've seen before include "Swift mammal" , "Old saying: 'Let the .... sit" , "Rabbit-like animal" , "Fast-running mammal" , "who often got stiff?" .)
