Instruction for gro_e; there's a line for you to work out (8,4)
I believe the answer is:
skipping rope
'work out' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'instruction for groe there's a line for you' is the wordplay.
I cannot quite see how this works, but
'there's' could be 'n' (I've seen this in other clues) and 'n' is located in the answer.
'line' could be 'rope' (rope is a kind of line) and 'rope' is found within the answer.
This may be the basis of clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for skipping rope that I've seen before include "toy" , "Item avoided during play" , "Training aid" , "equipment used when jumping" , "Cord with handles for jumping over" .)
