Maui welcome (5)
I believe the answer is:
aloha
'maui welcome' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aloha that I've seen before include "Welcome to Honolulu!" , "16 across in Hawaii" , "Hi! in Honolulu" , "Hawaiian "ciao"" , "Hawaiian greeting" .)
