Scottish monarch and American subject receiving British honour (7)
I believe the answer is:
macbeth
'scottish monarch and american' is the definition.
I can't judge whether this defines the answer.
'subject receiving british honour' is the wordplay.
'subject' becomes 'math' (math is a kind of subject).
'receiving' is an insertion indicator.
'british honour' becomes 'cbe' (I am not sure about the 'british' bit.**).
'math' placed around 'cbe' is 'MACBETH'.
Can you help me to learn more?
(Other definitions for macbeth that I've seen before include "play with tragic results" , "Shakespeare's Scottish play, considered unlucky" , "from 6 & 12 VERDI & SHAKESPEARE] ?" , "King of Scotland, 1040-1057" , "Scottish ruler" .)
