One who bows and scrapes? (9)
I believe the answer is:
violinist
'one who bows and scrapes?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
This is the entire clue.
Can you help me to learn more?
(Other definitions for violinist that I've seen before include "One mostly uses the bow" , "Stern, for example" , "I'll shoulder my equipment" , "Musician" , "Fiddler" .)
