Garland from the French island (3)
I believe the answer is:
lei
'garland' is the definition.
('lei' can be a synonym of 'garland')
'the french island' is the wordplay.
'the french' becomes 'le'.
'island' becomes 'i'.
'le'+'i'='LEI'
'from' acts as a link.
(Other definitions for lei that I've seen before include "Band of flowers" , "change in E. Europe" , "Hawaiian wreath" , "Hawaiian necklace of flowers" , "Flower arrangements" .)
