Ready to accept unimaginative cut in revised course (9)
I believe the answer is:
credulous
'ready' is the definition.
Both the answer and definition are adjectives. Maybe you can see a link between them that I can't see?
'to accept unimaginative cut in revised course' is the wordplay.
'to accept' is an insertion indicator.
'unimaginative cut in' becomes 'dul' (I can't explain this - if you can you should give a lot more credence to this answer).
'revised' is an anagram indicator.
'course' is an anagram of 'creous'.
'dul' put into 'creous' is 'CREDULOUS'.
Can you help me to learn more?
(Other definitions for credulous that I've seen before include "Apt to believe without sufficient evidence" , "Easily fooled" , "Likely to believe" , "Gullible" , "Too ready to believe things" .)
