Lots of cars very loud, I found aboard reversing vehicle (7)
I believe the answer is:
traffic
'lots of cars' is the definition.
'traffic' can be an answer for 'cars'. I'm not certain of the 'lots of' bit.
'loud i found aboard reversing vehicle' is the wordplay.
'loud' becomes 'ff' (musical abbreviation for fortissimo, very loud).
'found aboard' indicates putting letters inside (inserted letters come on board).
'reversing' shows that the letters should be reversed in order.
'vehicle' becomes 'cart' (cart is a kind of vehicle).
'cart' in reverse letter order is 'trac'.
'ff'+'i'='ffi'
'ffi' going inside 'trac' is 'TRAFFIC'.
'very' is the link.
Can you help me to learn more?
(Other definitions for traffic that I've seen before include "Moving vehicles; trade" , "Vehicles moving on public highways" , "Vehicles coming and going" , "Deal illegally in vehicles?" , "Passing vehicles - trade" .)
