Bother a servant with stationary item (6)
I believe the answer is:
eraser
'stationary item' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'bother a servant with' is the wordplay.
'with' indicates the answer is hidden within the clue.
'ERASER' is hidden in the letters of 'bother a servant'.
Can you help me to learn more?
(Other definitions for eraser that I've seen before include "India rubber" , "One who removed" , "One removes writing" , "Rubs out" , "Stationery item" .)
