Glorious, illustrious (8)
I believe the answer is:
splendid
I believe this is a double definition.
'glorious' is the first definition.
(synonyms)
'illustrious' is the second definition.

(Other definitions for splendid that I've seen before include "Magnificent, glorious" , "Wonderful" , "Marvellous" , "Great" , "Wicked" .)
