Left quickly, confused after desk rearranged (10)
I believe the answer is:
skedaddled
'left quickly' is the definition.
The definition and answer can be both to do with motion as well as being past participle verbs.
Maybe you can see an association between them that I don't see?
'confused after desk rearranged' is the wordplay.
'confused' becomes 'addled' (addling is a kind of confusing).
'after' is a charade indicator (letters next to each other).
'rearranged' indicates anagramming the letters.
'desk' with letters rearranged gives 'sked'.
'addled' after 'sked' is 'SKEDADDLED'.
Can you help me to learn more?
(Another definition for skedaddled that I've seen is " Ran off hurriedly".)
