See eye to eye with a native of Corfu largely (5)
I believe the answer is:
agree
'see eye to eye with' is the definition.
(seeing eye to eye is agreeing with someone)
'a native of corfu largely' is the wordplay.
'native of corfu' becomes 'Greek' (Corfu is a Greek island).
'largely' means to remove the last letter.
'greek' with its last letter removed is 'gree'.
'a'+'gree'='AGREE'
(Other definitions for agree that I've seen before include "Go along with" , "Hold the same view" , "suit" , "concede" , "chime?" .)
