Deliberately missing work to stuff extremely rude child's plaything (8,4)
I believe the answer is:
skipping rope
'child's plaything' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'deliberately missing work to stuff extremely rude' is the wordplay.
'deliberately missing' becomes 'skipping' (skipping is a kind of missing. I am not sure about the 'deliberately' bit.**).
'work' becomes 'op' (abbreviation for opus).
'to stuff' indicates putting letters inside.
'extremely' says to hollow out the word (remove centre letters).
'rude' with its centre taken out is 're'.
'op' going inside 're' is 'rope'.
'skipping'+'rope'='skippingrope'
Can you help me to learn more?
(Other definitions for skipping rope that I've seen before include "Item avoided during play" , "Training aid" , "equipment used when jumping" , "Cord with handles for jumping over" , "toy" .)
