Impassive social misfit gets time (7)
I believe the answer is:
stoical
'impassive' is the definition.
(I've seen this before)
'social misfit gets time' is the wordplay.
'misfit' is an anagram indicator (I've seen 'misfits' mean this (I've seen this in other clues)).
'gets' means one lot of letters goes inside another (gets can mean captures or absorbs).
'time' becomes 't' (abbreviation).
'social' is an anagram of 'soical'.
'soical' enclosing 't' is 'STOICAL'.
(Other definitions for stoical that I've seen before include "Indifferent to pain and pleasure" , "Uncomplaining in the face of adversity" , "Seeming to be unaffected by pleasure or pain" , "resigned to suffering" , "able to endure suffering" .)
