This poet makes uninteresting study (6)
I believe the answer is:
dryden
'this poet' is the definition.
(John Dryden)
'uninteresting study' is the wordplay.
'uninteresting' becomes 'dry' (I've seen this before).
'study' becomes 'den' (term for a study or office).
'dry'+'den'='DRYDEN'
'makes' acts as a link.
(Other definitions for dryden that I've seen before include "John --, first Poet Laureate" , "17th-century poet" , "playwright" , "Dry Ned, the strange English poet" , "man behind lines?" .)
