It may be indicative of little angels (8,4)

I believe the answer is:

telltale sign

I'm a little stuck... Click here to teach me more about this clue!

'it may be indicative' is the definition.
I know nothing about this answer so I can't judge whether this works.

'of little angels' is the wordplay.
'of' indicates anagramming the letters (the answer comes from or 'of' the letters).
'little'+'angels'='littleangels'
'littleangels' with letters rearranged gives 'TELLTALE SIGN'.

Can you help me to learn more?
