Bury in virgin territory (5)
I believe the answer is:
inter
'bury' is the definition.
('inter' can be a synonym of 'bury')
'in virgin territory' is the wordplay.
'in' indicates a hidden word.
'INTER' is hidden within 'virgin territory'.
(Other definitions for inter that I've seen before include "Plant" , "Lay to rest" , "somewhere between ..." , "Send to ground" , "foreign team" .)
