Monsieur in Lebanon walloped count? (8)
I believe the answer is:
nobleman
'count?' is the definition.
(count is a kind of nobleman)
'monsieur in lebanon walloped' is the wordplay.
'monsieur' becomes 'm'.
'in' means one lot of letters goes inside another.
'walloped' indicates anagramming the letters (I've seen 'wallop' mean this).
'lebanon' with letters rearranged gives 'noblean'.
'm' inserted inside 'noblean' is 'NOBLEMAN'.
(Other definitions for nobleman that I've seen before include "Male aristocrat" , "Member of the aristocracy" , "count, perhaps" , "Earl, say" , "Titled person" .)
