Handcart (6)
I believe the answer is:
barrow
'handcart' is the definition.
(barrow is a kind of handcart)
This is the entire clue.
(Other definitions for barrow that I've seen before include "Cart for one of the three sisters" , "Cumbrian town" , "Small cart for a prehistoric burial mound" , "Ancient burial mound" , "where items are sold" .)
