Guardians taking wrong angles (6)
I believe the answer is:
angels
'guardians' is the definition.
(I have seen 'Heavenly guardians ' mean 'angels' so perhaps 'guardians' could also mean 'angels')
'wrong angles' is the wordplay.
'wrong' is an anagram indicator.
'angles' with letters rearranged gives 'ANGELS'.
'taking' acts as a link.
(Other definitions for angels that I've seen before include "Gleans that they're heavenly" , "Charlie's - - (TV)" , "Theatrical investors" , "Misprint" , "Heavenely guardians" .)
