Hawaiian "shalom" (5)
I believe the answer is:
aloha
'hawaiian shalom' 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!" , "A Hawaiian welcome" , "A greeting in Hawaii" , "A Polynesian hello or goodbye" , "16 across in Hawaii" .)
