Blessed, sacrosanct (4)
I believe the answer is:
holy
This clue 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" .)
