Wearing halo, getting a greeting (5)
I believe the answer is:
aloha
'greeting' is the definition.
(I've seen this before)
'wearing halo getting a' is the wordplay.
'wearing' indicates an anagram (wear can mean to become damaged).
'getting' means one lot of letters go next to another.
'halo' with letters rearranged gives 'aloh'.
'aloh'+'a'='ALOHA'
(Other definitions for aloha that I've seen before include "A greeting in Hawaii" , "Hawaiian hello or goodbye" , "Hello from Honolulu?" , "A Polynesian hello or goodbye" , "Hello or goodbye in Hawaii" .)
