Poet makes boring study (6)
I believe the answer is:
dryden
'poet' is the definition.
(John Dryden)
'boring study' is the wordplay.
'boring' becomes 'dry' (dry can mean dull or boring).
'study' becomes 'den' (term for a study or office).
'dry'+'den'='DRYDEN'
'makes' is the link.
(Other definitions for dryden that I've seen before include "Dry Ned, the strange English poet" , "Amphitryon was his" , "English Restoration poet" , "John --, English 17th-cent. poet/dramatist" , "Poet laureate, 1668-1689" .)
