Be wrong in giving a growl going to earth (3)
I believe the answer is:
err
'be wrong' is the definition.
(to err is make an error)
'giving a growl going to earth' is the wordplay.
'giving a growl' becomes 'rr' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'going to' means one lot of letters go next to another.
'earth' becomes 'E'.
'rr' after 'e' is 'ERR'.
'in' is the link.
Can you help me to learn more?
(Other definitions for err that I've seen before include "'to... is human,to forgive divine'" , "Be incorrect" , "have an affair?" , "Blunder" , "Make mistakes" .)
