Vehicle, one I would precede, on which to go around (4)
I believe the answer is:
jeep
'vehicle one i would precede on which to go around' is the definition.
'jeep' can be an answer for 'vehicle' (jeep is a kind of vehicle). I am unsure of the remainder of the definition.
'on which to go around' is the wordplay.
'on' is a charade indicator (letters next to each other).
'which' becomes 'j' (I can't justify this - if you can you should give a lot more credence to this answer).
'to go' becomes 'pee' (both can mean to urinate).
'around' says the letters should be written in reverse.
'pee' written backwards gives 'eep'.
'j'+'eep' is 'JEEP'.
Can you help me to learn more?
(Other definitions for jeep that I've seen before include "Four-wheel-drive general purpose vehicle" , "Vehicle for rough terrain" , "Vehicle for rough ground" , "Army vehicle, 4-wheel drive" , "Truck" .)
