Leis woven in Hawaii, perhaps (4)
I believe the answer is:
isle
'hawaii perhaps' is the definition.
(Hawaii is an island)
'leis woven' is the wordplay.
'woven' indicates anagramming the letters.
'leis' anagrammed gives 'ISLE'.
'in' acts as a link.
(Other definitions for isle that I've seen before include "Insular place" , "This is sceptred!" , "Isolated land" , "Fair ---, knitting style" , "Anglesey, say" .)
