Blessed, sacrosanct (4)
I believe the answer is:
holy
I believe this is a double definition.
'blessed' is the first definition.
(similar in meaning)
'sacrosanct' is the second definition.
(I've seen this in another clue)
(Other definitions for holy that I've seen before include "perfect, morally and spiritually" , "Sacrosanct" , "Hallowed" , "Divine" , "Charlemagne was the first" .)
