Bury shrouds for one, two or three? (7)
I believe the answer is:
'two or three?' is the definition.
(I've seen this in another clue)
'bury shrouds for one' is the wordplay.
'bury' becomes 'inter' (to inter is to put into the ground).
'shrouds' indicates putting letters inside (shrouds can mean covers or contains).
'for one' becomes 'eg' (both can mean 'for example').
'inter' enclosing 'eg' is 'INTEGER'.
(Other definitions for integer that I've seen before include "one or two, perhaps" , "Perhaps 60,000" , "Result of counting" , "Get Erin (anag)" , "rational number remains" .)
