Peer coming ahead of time stopped prematurely (4)
I believe the answer is:
earl
'peer' is the definition.
(I know that earl is a type of peer)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for earl that I've seen before include "Lear (anag)" , "One who's been elevated" , "A lord like Lear" , "Real kind of English lord" , "Essex, say" .)
