Flawlessly (9)

Ross

I believe the answer is:

perfectly

'flawlessly' is the definition.
(thesaurus)

This is all the clue.

(Other definitions for perfectly that I've seen before include "Completely and without qualification" , "In a faultless way" , "In an ideal way" , "Absolutely, faultlessly" .)

I've seen this clue in the Evening Standard and the Newsday.
