Disinclined (6)
I believe the answer is:
averse
'disinclined' is the definition.
(similar in meaning)
This is the entire clue.
(Other definitions for averse that I've seen before include "'Opposed, disinclined (6)'" , "Disinclined, loath" , "Hostile" , "Reaves (anag)" , "A line of poetry is opposed" .)
