Song about coral destruction (5)
I believe the answer is:
carol
'song' is the definition.
(I know that carol is a type of song)
'coral destruction' is the wordplay.
'destruction' indicates an anagram.
'coral' is an anagram of 'CAROL'.
'about' acts as a link.
(Other definitions for carol that I've seen before include "See 1" , "Girl" , "Song celebrating the birth of Jesus" , "Religious song - girl's name" , "Joyful song - girl's name" .)
