Journalist occupying hospital chair (5)
I believe the answer is:
sedan
'chair' is the definition.
(sedan chair is a type of chair)
'journalist occupying hospital' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'occupying' indicates putting letters inside (inserted letters occupy or enter the word).
'hospital' becomes 'san' (short for sanatorium).
'ed' inserted within 'san' is 'SEDAN'.
(Other definitions for sedan that I've seen before include "Covered chair carried between poles" , "Where Prussians defeated French" , "outmoded form of transport" , "Chair; car" , "Enclosed chair" .)
