...and body after beheading is thereabouts (2,2)
I believe the answer is:
or so
'thereabouts' is the definition.
(I've seen this in another clue)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for or so that I've seen before include "roughly" , "Something like" , "Approximately" , "More or less" .)
