Roger says this works (8)
I believe the answer is:
receiver
'roger says this works' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
This is the entire clue.
Can you help me to learn more?
(Other definitions for receiver that I've seen before include "Equipment to take radio or tv signals" , "Beneficiary; fence" , "Telephone handset" , "Fence; bankruptcy official" , "One talked into" .)
