Cretan, say, sees land rise, worried (8)
I believe the answer is:
islander
'cretan say' is the definition.
(I know that Cretan is a type of islander)
'land rise worried' is the wordplay.
'worried' is an anagram indicator (worry can mean to interfere with or disturb).
'land'+'rise'='landrise'
'landrise' with letters rearranged gives 'ISLANDER'.
'sees' acts as a link.
(Other definitions for islander that I've seen before include "One living away from mainland" , "Samoan, Sardinian, Sumatran etc" , "Inhabitant of Skye, say" , "one from Jersey, perhaps" , "One from e.g. Skye" .)
