Monarch on real difference from Shakespearean work (4,4)
I believe the answer is:
king lear
'shakespearean work' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'monarch on real difference' is the wordplay.
'monarch' becomes 'king' (king is a kind of monarch).
'on' means one lot of letters goes inside another.
'difference' indicates an anagram.
'real' anagrammed gives 'lear'.
'king' placed into 'lear' is 'KING LEAR'.
'from' is the link.
Can you help me to learn more?
(Other definitions for king lear that I've seen before include "Shakespeare tragedy" , "One of Shakespeare's tragedies" , "Tragic Shakespearean monarch" , "Play set in medieval Britain" , "Shakespeare play with storm scene" .)
