Whole number, for example, in Bury (7)
I believe the answer is:
integer
'whole number' is the definition.
(synonyms)
'example in bury' is the wordplay.
'example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'in' indicates putting letters inside.
'bury' becomes 'inter' (to inter is to put into the ground).
'eg' going into 'inter' is 'INTEGER'.
'for' acts as a link.
(Other definitions for integer that I've seen before include "Gin tree (anag)" , "rational number remains" , "Perhaps 60,000" , "A whole number, not a fraction" , "Say one" .)
