No longer terribly crude? (5)
I believe the answer is:
cured
'no longer terribly crude?' is the definition.
Both the definition and answer are adjectives. Maybe you can see an association between them that I don't see?
'terribly crude?' is the wordplay.
'terribly' is an anagram indicator.
'crude' anagrammed gives 'CURED'.
Can you help me to learn more?
(Other definitions for cured that I've seen before include "Made better or preserved" , "Successfully treated" , "Freed of disease" , "Of ham, smoked or salted" , "Made well" .)
