Fragmented result of cutting through a wood (7)
I believe the answer is:
sawdust
'wood' is the definition.
(I know that sawdust is a type of wood)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for sawdust that I've seen before include "result of use of blade" , "Fine particles from cut wood" , "Carpenters' output" , "Shavings on the floor" , "remains in the workshop" .)
