He has contrived renown pointlessly (5)
I believe the answer is:
owner
'he has' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for owner that I've seen before include "Possessor, proprietor" , "Keeper" , "One that secured" , "possessive type" , "Man of property" .)
