Deception about good deal in office equipment (10)
I believe the answer is:
guillotine
'office equipment' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'deception about good deal in' is the wordplay.
'deception' becomes 'guile' (guile is a kind of deception).
'about' indicates putting letters inside.
'good deal' becomes 'lot' (a good deal of something).
'lot'+'in'='lotin'
'guile' enclosing 'lotin' is 'GUILLOTINE'.
Can you help me to learn more?
(Other definitions for guillotine that I've seen before include "Top" , "Beheading machine" , "One with sharp blade" , "Head-removing device" , "revolutionary chopper" .)
