They may fly off at various angles (6)
I believe the answer is:
angels
'they may fly off' is the definition.
The definition suggests an adverb but the answer is not.
'various angles' is the wordplay.
'various' is an anagram indicator.
'angles' is an anagram of 'ANGELS'.
'at' is the link.
Can you help me to learn more?
(Other definitions for angels that I've seen before include "Theatrical investors" , "Heavenely guardians" , "Financial backers, esp theatrical" , "Heavenly guardians" , "Gleans that they're heavenly" .)
