Claud reformed with grace (5)

I believe the answer is:

ducal

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

'claud reformed with grace' is the definition.
I can't judge whether this defines the answer.

'claud reformed' is the wordplay.
'reformed' is an anagram indicator.
'claud' with letters rearranged gives 'DUCAL'.

Can you help me to learn more?

(Other definitions for ducal that I've seen before include "of Wellingtons?" , "Peer's" , "Relating to a high peer" , "Representing noble" , "High-ranking" .)

I've seen this clue in The Globe and Mail.
