Corrected in crude style (5)
I believe the answer is:
cured
'corrected in' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Maybe you can see an association between them that I don't see?
'crude style' is the wordplay.
'style' is an anagram indicator (style can mean to shape or design).
'crude' with letters rearranged gives 'CURED'.
Can you help me to learn more?
(Other definitions for cured that I've seen before include "Restored to health" , "Freed of disease" , "Healed - smoked" , "Made well" , "Remedied" .)
