Mischievous Mike pulling out of parade (4)
I believe the answer is:
arch
'mischievous' is the definition.
(arch can mean mischievous or playful)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for arch that I've seen before include "Knowing, sly" , "Wellington's, perhaps" , "which may fall and inconvenience walkers" , "(archaic)" , "Curve of the foot" .)
