Instruments left on vehicles in Darwin (5)
I believe the answer is:
lutes
'instruments left' is the definition.
'lutes' can be an answer for 'instruments' (I've seen this before). I am not certain of the 'left' bit.
'on vehicles in darwin' is the wordplay.
'on' means one lot of letters go next to another.
'vehicles' becomes 'utes' (I've seen this before).
'in darwin' becomes 'l' (I can't justify this - if you can you should give a lot more credence to this answer).
'utes' after 'l' is 'LUTES'.
Can you help me to learn more?
(Another definition for lutes that I've seen is " Old stringed instruments".)
