Bother a servant about stationery item (6)
I believe the answer is:
eraser
'stationery item' is the definition.
(I've seen this before)
'bother a servant about' is the wordplay.
'about' says the answer is hidden in the clue.
'ERASER' is hidden in the letters of 'bother a servant'.
(Other definitions for eraser that I've seen before include "Obliterator" , "It could remove" , "Piece of rubber for deleting pencil marks" , "Rubber, thing that wipes out" , "One who removed" .)
