Wrong place for the van (4)
I believe the answer is:
rear
'wrong place' is the definition.
'rear' can be an answer for 'place' (rear is a kind of place). I am not certain of the 'wrong' bit.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for rear that I've seen before include "Raise - back" , "what can be brought up, finally" , "Of horse, rise up on hind legs" , "Rise up at the back" , "Raise; behind" .)
