Islanders can rest in resort (7)
I believe the answer is:
cretans
'islanders' is the definition.
The definition and answer can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'can rest in resort' is the wordplay.
'in resort' is an anagram indicator (the letters are re-sorted).
'can'+'rest'='canrest'
'canrest' with letters rearranged gives 'CRETANS'.
Can you help me to learn more?
(Another definition for cretans that I've seen is " These islanders".)
