'islander' is the definition.
(Cyprus is an island)

I cannot understand how the remainder of the clue works.

(Other definitions for cypriot that I've seen before include "One from Larnaka, say" , "One from Paphos, say" , "Nationality of citizen of Nicosia" , "One from Larnaca, say" , "Eg, a native of Nicosia" .)

I've seen this clue in the Evening Standard.
