Map of Hawaii, often (5)
I believe the answer is:
inset
'map of hawaii often' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for inset that I've seen before include "one image within another" , "Small piece inserted" , "Synagogue singer" , "Extra bit of garment" , "Extra page or piece added to enlarge" .)
