"Dulce et Decorum Est" poet (4)
I believe the answer is:
'dulce et decorum est poet' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for owen that I've seen before include "English war poet, killed 1918" , "Wilfred - - , WW1 poet" , "Welsh boy's name" , "Welsh industrialist and social reformer, founder of cooperative communities, d. 1858" , "Clive --, English actor" .)
