Linda's resettled in Corfu, say (6)
I believe the answer is:
island
'corfu say' is the definition.
(Corfu is an example of an island)
'linda's resettled' is the wordplay.
'resettled' indicates anagramming the letters (letters must be resettled in a new order).
'lindas' is an anagram of 'ISLAND'.
'in' acts as a link.
(Other definitions for island that I've seen before include "Small land mass" , "Area in the main" , "See 7" , "Boffin, Baffin or Barbados" , "Barbados, say" .)
