Shakespearean villain one with a company around him (7)
I believe the answer is:
'shakespearean villain' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'one with a company around him' is the wordplay.
'one' becomes 'i' (Roman numeral).
'with' means one lot of letters go next to another.
'company' becomes 'co' (abbreviation).
'around' indicates putting letters inside.
'co' going around 'him' is 'chimo'.
Can you help me to learn more?
(Other definitions for iachimo that I've seen before include "role in Cymbeline" , "Shakespearean character" .)
