Hospital department facing rebuke for trick (6)
I believe the answer is:
entrap
'trick' is the definition.
(I've seen this before)
'hospital department facing rebuke' is the wordplay.
'hospital department' becomes 'ent'.
'facing' says to put letters next to each other.
'rebuke' becomes 'rap' (rap is a kind of rebuke).
'ent'+'rap'='ENTRAP'
'for' is the link.
(Other definitions for entrap that I've seen before include "Lure into wrongdoing in order to arrest" , "Catch like parent" , "Snare, trick" , "Trepan (anag.)" , "Take" .)
