Its unlikely that a mischievous child can be dressed (10)
I believe the answer is:
improbable
'unlikely that a mischievous child can be dressed' is the definition.
'improbable' can be an answer for 'unlikely' (I've seen this before). I'm unsure of the remainder of the definition.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for improbable that I've seen before include "Highly unlikely" , "Far-fetched" , "Not likely" .)
