Hill cart in Cumbrian town (6)
I believe the answer is:
barrow
This clue is a triple definition!
'hill' is the first definition.
(I know that barrow is a type of burial mound)
'cart' is the second definition.
(barrow is a kind of cart)
'in' acts as a link.
'cumbrian town' is the third definition.
(Barrow-on-Furness is a town in Cumbria)
(Other definitions for barrow that I've seen before include "Ancient burial mound" , "Cart; tumulus" , "Grave mound - wheeled handcart" , "where items are sold" , "One-wheeled handcart" .)
