Playful fool's crime out of order (10)
I believe the answer is:
frolicsome
'playful' is the definition.
('frolicsome' can be similar in meaning to 'playful')
'fool's crime out of order' is the wordplay.
'out of order' indicates an anagram.
'fools'+'crime'='foolscrime'
'foolscrime' anagrammed gives 'FROLICSOME'.
(Other definitions for frolicsome that I've seen before include "Lively, playful" , "Enjoying a prank" .)
