Garlands from exotic isle? (4)
I believe the answer is:
leis
'garlands' is the definition.
('lei' can be a synonym of 'garland')
'exotic isle?' is the wordplay.
'exotic' indicates an anagram (an unusual form of the letters).
'isle' anagrammed gives 'LEIS'.
'from' is the link.
(Other definitions for leis that I've seen before include "Isle (anag) - Polynesian garlands" , "Hawaiian garlands" .)
