Channel features film showing home for the terminally ill (7)
I believe the answer is:
hospice
'home for the terminally ill' is the definition.
(I've seen this before)
'channel features film' is the wordplay.
'channel' becomes 'hose' (hose is a kind of channel).
'features' indicates putting letters inside.
'film' becomes 'pic' (short for picture).
'hose' enclosing 'pic' is 'HOSPICE'.
'showing' is the link.
(Other definitions for hospice that I've seen before include "Home for the care of the terminally ill" , "Home providing care for the sick" , "Religious lodging" , "Medical and emotional programme for the terminally ill" , "Ice shop (anag.)" .)
