Second instrument? (6)
I believe the answer is:
fiddle
This might be a double definition.
'second' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'instrument?' is the second definition.
(fiddle is a kind of instrument)
Can you help me to learn more?
(Other definitions for fiddle that I've seen before include "Violin; falsify (figures)" , "Scam - musical instrument" , "The poor man's violin" , "Stringed instrument - cheat" , "Deception" .)
