Turkey imprisons a revolutionary individual to make a point (5)
I believe the answer is:
tenor
'a point' is the definition.
(thesaurus)
'turkey imprisons a revolutionary individual' is the wordplay.
'turkey' becomes 'tr' (abbreviation eg in internet addresses).
'imprisons' is an insertion indicator.
'a revolutionary' says the letters should be written backwards.
'individual' becomes 'one' (an individual is one person).
'one' back-to-front is 'eno'.
'tr' going around 'eno' is 'TENOR'.
'to make' is the link.
(Other definitions for tenor that I've seen before include "Carreras, for example" , "Male singer with high-pitched voice" , "theme" , "Placido Domingo, say" , "Higher male voice" .)
