Mischievous lad, eight, stepped down (8)
I believe the answer is:
alighted
'stepped down' is the definition.
The answer and definition can be both to do with motion as well as being past participle verbs.
Maybe there's a link between them I don't understand?
'mischievous lad eight' is the wordplay.
'mischievous' indicates an anagram.
'lad'+'eight'='ladeight'
'ladeight' anagrammed gives 'ALIGHTED'.
Can you help me to learn more?
(Other definitions for alighted that I've seen before include "Dismounted" , "Moved to platform" , "Came down" , "Got down from, plane or train" , "Got down from, bus or train" .)
