Number, for example, in Bury (7)
I believe the answer is:
integer
'number' is the definition.
(integer is a kind of number)
'example in bury' is the wordplay.
'example' becomes 'eg'.
'in' is an insertion indicator.
'bury' becomes 'inter' (synonyms).
'eg' inserted into 'inter' is 'INTEGER'.
'for' is the link.
(Other definitions for integer that I've seen before include "Gin tree (anag)" , "Say one" , "Perhaps 60,000" , "A whole number, not a fraction" , "One for example" .)
