Regal, grand (8)
I believe the answer is:
majestic
I believe this is a double definition.
'regal' is the first definition.
(I know that regal can be written as majestic)
'grand' is the second definition.
(I've seen this before)
(Other definitions for majestic that I've seen before include "Of noble bearing, like a king" , "August" , "Of royal appearance or status" , "Regal, imperial" , "Regal - stately" .)
