Amazing; magnificent (3-9)
I believe the answer is:
awe-inspiring
I believe this is a double definition.
'amazing' is the first definition.
(synonyms)
'magnificent' is the second definition.
(thesaurus)
(Other definitions for awe-inspiring that I've seen before include "Invoking wonder" , "Magnificent" , "Astonishing" , "Terribly impressive" , "Breathtaking" .)
