Stringed instrument, awful noise (6)
I believe the answer is:
racket
This clue might be a double definition.
'stringed instrument' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'awful noise' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for racket that I've seen before include "Cowboy contest" , "Clamour; tennis bat" , "noise pollution" , "Din, clamour" , "sporting gear ..." .)
