Hello: a greeting abroad taken the wrong way? (5)
I believe the answer is:
aloha
'hello' is the definition.
(I've seen this in another clue)
'a greeting abroad taken the wrong way?' is the wordplay.
'greeting abroad' becomes 'hola' (I've seen this in another clue).
'taken the wrong way?' says the letters should be written backwards.
'a'+'hola'='ahola'
'ahola' written backwards gives 'ALOHA'.
(Other definitions for aloha that I've seen before include "A greeting in Hawaii" , "Hawaiian "ciao"" , "16 across in Hawaii" , "A Polynesian hello or goodbye" , "Hello from Honolulu?" .)
