Being worn, can it cause a skid? (7)
I believe the answer is:
slipper
'it cause a skid?' is the definition.
The definition suggests a singular noun which matches the answer.
'being worn can' is the wordplay.
'being' becomes 'slip' (slip is a kind of being).
'worn can' becomes 'per' (I am not sure about this - if you are sure you should believe this answer much more).
'slip'+'per'='SLIPPER'
Can you help me to learn more?
(Other definitions for slipper that I've seen before include "Footwear item" , "Beat; mule" , "runner" , "Comfortable footwear" , "Casual indoors shoe" .)
