Chat in hospital kitchen (4)
I believe the answer is:
talk
'chat' is the definition.
(I've seen this in another clue)
'in hospital kitchen' is the wordplay.
'in' indicates the answer is hidden within the clue.
'TALK' is hidden within 'hospital kitchen'.
(Other definitions for talk that I've seen before include "Idle gossip" , "Conversation" , "Gossip - lecture" , "Discussion" , "Utter" .)
