Stop a lion running from a peer (8)
I believe the answer is:
baronial
'from a peer' is the definition.
I can't judge whether this definition defines the answer.
'stop a lion running' is the wordplay.
'stop' becomes 'bar' (bar can mean to stop or prevent).
'running' indicates an anagram (the letters run around to different places).
'a'+'lion'='alion'
'alion' anagrammed gives 'onial'.
'bar'+'onial'='BARONIAL'
Can you help me to learn more?
(Other definitions for baronial that I've seen before include "of the nobility" , "Pertaining to a peer of the lowest rank" , "Pertaining to a lower noble" , "Impressive in appearance" .)
