Poet in centre of Corfu (5)
I believe the answer is:
homer
'poet' is the definition.
(Homer is an example)
'in centre of corfu' is the wordplay.
'in' becomes 'home' ('he's in' can mean 'he's home').
'centre of' means to look at the middle letters.
The middle letter of 'corfu' is 'r'.
'home'+'r'='HOMER'
(Other definitions for homer that I've seen before include "Great Greek author of The Iliad" , "messenger of war?" , "successful run in America?" , "linesman" , "Greek poet, c. 800 BC" .)
