It has a remote connection with TV (7)
I believe the answer is:
control
This might be a double definition.
'it has a remote connection' is the first definition.
The definition suggests a singular noun which matches the answer.
'tv' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'with' acts as a link.
Can you help me to learn more?
(Other definitions for control that I've seen before include "Regulation" , "domination" , "Rule" , "Command, regulate" , "Corn lot (anag.)" .)
