Majestic sort of lager (5)
I believe the answer is:
regal
'majestic' is the definition.
(I know that majestic can be written as regal)
'sort of lager' is the wordplay.
'sort of' is an anagram indicator.
'lager' with letters rearranged gives 'REGAL'.
(Other definitions for regal that I've seen before include "King-like" , "Royal - 5 down (anag)" , "Grand and imposing" , "fit for the Queen" , "Imperial, majestic" .)
