Cancel transformation for Cinders? (7)

I believe the answer is:

rescind

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

'cancel' is the definition.
(to rescind is to cancel or repeal)

'transformation for cinders?' is the wordplay.
'cinders' anagrams to 'RESCIND'.
But, I'm not clear how the anagram is indicated.

Can you help me to learn more?

(Other definitions for rescind that I've seen before include "Annul - discern (anag)" , "Revoke (order)" , "Cancel (regulation)" , "Revoke (a law/order)" , "Cinders (anag.)" .)
