Booboo Hamish appeared to cover up (6)
I believe the answer is:
mishap
'booboo hamish appeared to cover up' is the definition.
I can't judge whether this definition defines the answer.
'booboo hamish appeared to cover' is the wordplay.
'to cover' says the answer is hidden in the clue (I've seen 'covered' mean this (the answer is covered up by the clue)).
'MISHAP' is hidden within 'booboo hamish appeared'.
Can you help me to learn more?
(Other definitions for mishap that I've seen before include "'Bad luck, mischance (6)'" , "Unfortunate occurrence" , "'Accident, bad luck (6)'" , "An accident or unlucky event" , "An accident, piece of bad luck" .)
