Reluctant to have a bit of poetry (6)
I believe the answer is:
averse
'reluctant' is the definition.
(I've seen this before)
'a bit of poetry' is the wordplay.
'bit of poetry' becomes 'verse'.
'a'+'verse'='AVERSE'
'to have' is the link.
(Other definitions for averse that I've seen before include "A line of poetry is opposed" , "Indisposed" , "Antipathetic" , "Disinclined - sounds like a poem" , "Strongly opposed (to something)" .)
