Stately, dignified (8)
I believe the answer is:
majestic
I believe this is a double definition.
'stately' is the first definition.
(I've seen this before)
'dignified' is the second definition.
(thesaurus)
(Other definitions for majestic that I've seen before include "August" , "'Regal, royal (8)'" , "Regal, imperial" , "Regal - stately" , "Grand, impressive" .)
