Bury for most of the winter (5)
I believe the answer is:
inter
'bury' is the definition.
(to inter is to put into the ground)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for inter that I've seen before include "Inhume" , "Milan FC" , "Milan football team" , "set underground" , "Football Club seen in Milan" .)
