Pardon clue ending in chaos (10)

I believe the answer is:

indulgence

'pardon' is the definition.
(thesaurus)

'clue ending in chaos' is the wordplay.
'in chaos' indicates an anagram.
'clue'+'ending'='clueending'
'clueending' anagrammed gives 'INDULGENCE'.

(Other definitions for indulgence that I've seen before include "leniency" , "Gratification, luxury" .)

I've seen this clue in The Telegraph.
