Versifier’s attempt produces verse (6)
I believe the answer is:
poetry
'verse' is the definition.
(synonyms)
'versifier's attempt' is the wordplay.
'versifier's' becomes 'poe' (I am not sure about this - if you are sure you should believe this answer much more).
'attempt' becomes 'try' (synonyms).
'poe'+'try'='POETRY'
'produces' acts as a link.
Can you help me to learn more?
(Other definitions for poetry that I've seen before include "Verses" , "Literary art" , "Literary genre" , "Lines" , "Sonnets, limericks etc" .)
