Island salutation reversing a greeting on Majorca? (5)
I believe the answer is:
aloha
'island salutation' is the definition.
(Hawaiian salutation)
'reversing a greeting on majorca?' is the wordplay.
'reversing' says the letters should be written in reverse.
'greeting on majorca?' becomes 'hola' (Spanish greeting).
'a'+'hola'='ahola'
'ahola' backwards is 'ALOHA'.
(Other definitions for aloha that I've seen before include "Hawaiian farewell" , "Hawaiian hello or goodbye" , "A Polynesian hello or goodbye" , "Hawaiian "ciao"" , "Hello from Honolulu?" .)
