Parking on meadow with rear of car covered in mist is child's play (8)
I believe the answer is:
leapfrog
'child's play' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'parking on meadow with rear of car covered in mist' is the wordplay.
'parking on meadow' becomes 'leap' (I can't explain this - if you can you should believe this answer much more).
'with' says to put letters next to each other.
'rear of' says to take the final letters.
'covered in' means one lot of letters goes inside another.
'mist' becomes 'fog' ('fog' can be a synonym of 'mist').
The last letter of 'car' is 'r'.
'r' inserted within 'fog' is 'frog'.
'leap'+'frog'='LEAPFROG'
'is' is the link.
Can you help me to learn more?
(Other definitions for leapfrog that I've seen before include "Advance by jumping over the opposition" , "Playground game" , "Child's game of jumping over competitors" , "Jump over" , "Game in which one child jumps over another" .)
