Opposed, disinclined (6)
I believe the answer is:
averse
This clue is a double definition.
'opposed' is the first definition.
(synonyms)
'disinclined' is the second definition.
(similar in meaning)
(Other definitions for averse that I've seen before include "Having a strong opposition (to)" , "A line of poetry is opposed" , "A piece of poetry is reluctant" , "Antipathetic" , "Disinclined - sounds like a poem" .)
