Honolulu greeting (5)
I believe the answer is:
aloha
'honolulu greeting' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aloha that I've seen before include "Hello from Honolulu?" , "Hawaiian hello or goodbye" , "Hawaiian farewell" , "Hello or goodbye in Hawaii" , "Welcome to Honolulu!" .)
