Induce rehabilitation in hospital department for TV watchers? (8)
I believe the answer is:
audience
'tv watchers?' is the definition.
'induce rehabilitation in hospital department' is the wordplay.
'rehabilitation' is an anagram indicator.
'in' is an insertion indicator.
'hospital department' becomes 'ae' (A&E, Accident & Emergency).
'induce' is an anagram of 'udienc'.
'udienc' put into 'ae' is 'AUDIENCE'.
'for' is the link.
(Other definitions for audience that I've seen before include "They observe" , "Group of spectators or listeners" , "Viewers - listeners" , "Theatre-goers" , "Formal meeting with the Pope" .)
