Learn about legless peer (4)
I believe the answer is:
earl
'peer' is the definition.
(I know that earl is a type of peer)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for earl that I've seen before include "A real sort of lord" , "Countess his wife" , "Lear (anag)" , "Peer (Br.)" , "Sandwich perhaps" .)
