Admit devouring English poet (4)
I believe the answer is:
owen
'poet' is the definition.
(I've seen this before)
'admit devouring english' is the wordplay.
'admit' becomes 'own' (own can mean to admit or acknowledge).
'devouring' indicates putting letters inside.
'english' becomes 'E' (abbreviation as in OED).
'own' placed around 'e' is 'OWEN'.
(Other definitions for owen that I've seen before include "Welsh boy's name" , "Clive --, English actor" , "Welsh industrialist and social reformer, founder of cooperative communities, d. 1858" , "Former SDP leader" , "Wilfred - - , WW1 poet" .)
