Homely entertainment (5)
I believe the answer is:
telly
'homely entertainment' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
This is all the clue.
Can you help me to learn more?
(Other definitions for telly that I've seen before include "TV (colloq.)" , "Familiar name for TV" , "cop in seventies" , "Set" , "Television" .)
