Bury battered tin with sovereign (5)
I believe the answer is:
inter
'bury' is the definition.
('inter' can be a synonym of 'bury')
'battered tin with sovereign' is the wordplay.
'battered' indicates an anagram.
'with' is a charade indicator (letters next to each other).
'sovereign' becomes 'er' (Abbreviation for Elizabeth Regina**).
'tin' is an anagram of 'int'.
'int'+'er'='INTER'
(Other definitions for inter that I've seen before include "Send to ground" , "Bury a body - in the middle?" , "Set deep" , "Nitre (anag.)" , "Lay to rest" .)
