Right-hander's shot to the right, a bit left!
I believe the answer is:
off cut
'left' is the definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for off cut that I've seen before include "Waste trimming" , "Small bit of some material" , "Bit left over" , "To cuff (anag.)" , "Piece of leftover material" .)
