Deep hatred for a soldier we hear (7)
I believe the answer is:
rancour
'deep hatred' is the definition.
'rancour' can be an answer for 'hatred' (rancour is a kind of hatred). I'm not certain of the 'deep' bit.
'a soldier we hear' is the wordplay.
'a soldier' becomes 'ranker' (ranker is a kind of soldier).
'we hear' indicates a 'sounds like' (homophone) clue.
'ranker' sounds like 'RANCOUR'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for rancour that I've seen before include "Long-lasting bitterness" , "Antipathy" , "Acrimony" , "Spite" , "Feeling of bitterness or dislike" .)
