One of several in ring who shows appreciation (7)
I believe the answer is:
clapper
This might be a double definition.
'one of several in ring' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'shows appreciation' is the second definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'who' acts as a link.
Can you help me to learn more?
(Other definitions for clapper that I've seen before include "part of the "Ring Cycle"?" , "The tongue or striker of a bell" , "Bell hitter" , "One vigorously using hands" , "That rings a bell" .)
