One that can hear large aristocrat (4)
I believe the answer is:
earl
'aristocrat' is the definition.
(earl is a kind of aristocrat)
'one that can hear large' is the wordplay.
'EARL' is hidden within the letters.
But, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for earl that I've seen before include "Rank below marquess" , "Noble title" , "A real titled lord" , "UK nobleman ranking between marquess and viscount" , "Sandwich perhaps" .)
