Generously treated pilots after a crash (6)
I believe the answer is:
spoilt
'generously treated' is the definition.
The answer and definition can be both related to change as well as being past participle verbs.
Maybe there's an association between them I don't understand?
'pilots after a crash' is the wordplay.
'after a crash' is an anagram indicator.
'pilots' with letters rearranged gives 'SPOILT'.
Can you help me to learn more?
(Other definitions for spoilt that I've seen before include "injured" , "Ruined" , "Deprived" , "Destroyed the value of" , "Harmed" .)
