Not complete home entertainment (5)
I believe the answer is:
telly
This could be a double definition.
'not complete home' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'entertainment' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
Can you help me to learn more?
(Other definitions for telly that I've seen before include "The goggle-box" , "One of the media" , "Familiar name for TV" , "cop in seventies" , "Set" .)
