Real stupid title-holder (4)
I believe the answer is:
earl
'title-holder' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'real stupid' is the wordplay.
'stupid' indicates anagramming the letters (in a stupid order).
'real' is an anagram of 'EARL'.
Can you help me to learn more?
(Other definitions for earl that I've seen before include "House member" , "Husband of a countess" , "Peer of the realm" , "Sandwich perhaps" , "Essex, say" .)
