Bury in hinterlands (5)
I believe the answer is:
inter
'bury' is the definition.
(to inter is to put into the ground)
'in hinterlands' is the wordplay.
'in' indicates the answer is hidden within the clue.
'INTER' can be found hidden inside 'hinterlands'.
(Other definitions for inter that I've seen before include "get put down!" , "Place in ground" , "Nitre (anag.)" , "Set deep" , "Milan football team" .)
