Made telephone ring (4)
I believe the answer is:
bell
This could be a double definition.
'made telephone' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'ring' is the second definition.
(both can mean to call on the phone)
Can you help me to learn more?
(Other definitions for bell that I've seen before include "He invented" , "Inventor - clanger" , "Wide end of a trumpet" , "ring" , "Boxing match signal" .)
