Sincerely love duty being amended (8)

Ross

I believe the answer is:

devoutly

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

'sincerely' is the definition.
Both the definition and answer are adverbs. Maybe they are linked in a way I don't understand?

'love duty being amended' is the wordplay.
'being amended' indicates an anagram.
'love'+'duty'='loveduty'
'loveduty' is an anagram of 'DEVOUTLY'.

Can you help me to learn more?

(Another definition for devoutly that I've seen is " Faithfully".)
