Dray (4)
I believe the answer is:
cart
'dray' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cart that I've seen before include "Something not to be put in front of the horse" , "Open vehicle" , "Old two-wheeled goods vehicle" , "Two-wheeled open wagon" , "Wheelbarrow" .)
