The morning help is easily won over (8)
I believe the answer is:
amenable
'easily won over' is the definition.
Both the answer and definition are adjectives. Perhaps you can see an association between them that I don't see?
'the morning help' is the wordplay.
'the morning' becomes 'am' (as in en:00 AM).
'help' becomes 'enable' (I can't explain this - if you can you should believe this answer much more).
'am'+'enable'='AMENABLE'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for amenable that I've seen before include "Open and responsive to suggestion" , "Willing to comply" , "Easily influenced" , "Open to suggestions" , "Compliant - persuadable" .)
