Reluctant to produce a few lines (6)
I believe the answer is:
averse
'reluctant' is the definition.
(thesaurus)
'a few lines' is the wordplay.
'few lines' becomes 'verse'.
'a'+'verse'='AVERSE'
'to produce' acts as a link.
(Other definitions for averse that I've seen before include "Not keen" , "Ill-disposed to (a poem?)" , "Having a strong dislike" , "Antipathetic" , "Unwilling or disinclined, perhaps to hard work" .)
