Place in the earth of hinterlands (5)
I believe the answer is:
inter
'place in the earth' is the definition.
(I've seen this in another clue)
'of hinterlands' is the wordplay.
'of' indicates a hidden word.
'INTER' can be found hidden inside 'hinterlands'.
(Other definitions for inter that I've seen before include "Bury a body - in the middle?" , "Lay to rest" , "Place in ground" , "Place into grave, tomb" , "Send to ground" .)
