Ring nun late in a state (7)

I believe the answer is:

annulet

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

'ring' is the definition.
(annulet is a kind of ring)

'nun late in a state' is the wordplay.
'nun late' can be anagrammed to 'ANNULET'.
Though, I'm unsure how this is indicated.

Can you help me to learn more?
