Figure to bury put outside empty grave (7)
I believe the answer is:
integer
'figure' is the definition.
(thesaurus)
'bury put outside empty grave' is the wordplay.
'bury' becomes 'inter' ('inter' can be a synonym of 'bury').
'put outside' is an insertion indicator.
'empty' says to hollow out the word (remove centre letters).
'grave' with its centre taken out is 'ge'.
'inter' going around 'ge' is 'INTEGER'.
'to' acts as a link.
(Other definitions for integer that I've seen before include "Perhaps 60,000" , "Gin tree (anag)" , "Get Erin (anag)" , "Whole unit" , "one or two, perhaps" .)
