Poet's appointment around noon (5)
I believe the answer is:
dante
'poet's' is the definition.
(Dante is an example)
'appointment around noon' is the wordplay.
'appointment' becomes 'date' ('date' can be a synonym of 'appointment').
'around' means one lot of letters goes inside another.
'noon' becomes 'n'.
'date' going around 'n' is 'DANTE'.
(Other definitions for dante that I've seen before include "Italian poet, 1265-1321" , "Great Italian poet of 'The Divine Comedy'" , "Finally stand before" , "Thirteenth to fourteenth century Italian poet" , "Poet inspired by Beatrice" .)
