Majestic part of the summer? (6)
I believe the answer is:
august
I believe this is a double definition.
'majestic' is the first definition.
(thesaurus)
'part of the summer?' is the second definition.
('August' is part of 'summer')
(Other definitions for august that I've seen before include "Majestic or imposing, like month" , "Dignified - time of year" , "Inspiring respect; month" , "Inspiring respect and admiration" , "Inspiring reverence" .)
