Opposed to some poetry (6)
I believe the answer is:
averse
'opposed to' is the definition.
(I've seen this in another clue)
'some poetry' is the wordplay.
'some' becomes 'a'.
'poetry' becomes 'verse' (lines written in verse).
'a'+'verse'='AVERSE'
(Other definitions for averse that I've seen before include "Having a strong dislike" , "Indisposed" , "Ill-disposed to (a poem?)" , "Antipathetic" , "Unwilling or disinclined, perhaps to hard work" .)
