One ends around a bit of poetry to survey (7)
I believe the answer is:
oversee
'to survey' is the definition.
(I've seen this before)
'one ends around a bit of poetry' is the wordplay.
'ends' suggests removing the centre.
'around' means one lot of letters goes inside another.
'a bit of poetry' becomes 'verse' (verse means poetry).
'one' with its middle removed is 'oe'.
'oe' placed around 'verse' is 'OVERSEE'.
(Other definitions for oversee that I've seen before include "Superintend, manage" , "Watch people toil" , "Administer" , "Supervise officially" , "Be responsible for" .)
