Treason, maybe, in politics (7)
I believe the answer is:
senator
'politics' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'treason maybe' is the wordplay.
'maybe' is an anagram indicator.
'treason' is an anagram of 'SENATOR'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for senator that I've seen before include "Legislator -- treason (anag)" , "American politician" , "Roman politician" , "Legislative body member" , "Member of upper house of legislature" .)
