Is it played dishonestly? (6)
I believe the answer is:
fiddle
'it played dishonestly?' is the definition.
The definition suggests a singular noun which matches the answer.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for fiddle that I've seen before include "Stringed instrument - cheat" , "Violin; falsify (figures)" , "Get by cheating, or handle aimlessly" , "Swindle the musical instrument" , "Steal from one's employer" .)
