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' says the answer is hidden in the clue.
'INTER' is hidden within 'hinterlands'.
(Other definitions for inter that I've seen before include "get put down!" , "Place in ground" , "Nitre (anag.)" , "Set deep" , "Milan football team" .)
