A number having wage cut by half in Bury (7)
I believe the answer is:
integer
'a number' is the definition.
(I know that integer is a type of number)
'wage cut by half in bury' is the wordplay.
'cut by half' indicates taking half.
'in' means one lot of letters goes inside another.
'bury' becomes 'inter' (to inter is to put into the ground).
'wage' halved is 'ge'.
'ge' inserted inside 'inter' is 'INTEGER'.
'having' acts as a link.
(Other definitions for integer that I've seen before include "Treeing (anag.)" , "rational number remains" , "A whole number, not a fraction" , "Say one" , "Result of counting" .)
