Let special medical team cut open Marxist? (6)
I believe the answer is:
rented
'let' is the definition.
(thesaurus)
'special medical team cut open marxist?' is the wordplay.
'special medical team' becomes 'ent' (abbreviation for Ear, Nose and Throat department).
'cut open' indicates putting letters inside.
'marxist?' becomes 'red' ('red' can be a synonym of 'marxist').
'ent' going inside 'red' is 'RENTED'.
(Other definitions for rented that I've seen before include "Taken for hire" , "Hired - tender (anag)" , "Leased" , "Let for money" .)
