Amazing; unreal (9)
I believe the answer is:
fantastic
I believe this is a double definition.
'amazing' is the first definition.
(I've seen this before)
'unreal' is the second definition.
(thesaurus)
(Other definitions for fantastic that I've seen before include "Fanciful" , "Marvellous" , "Brilliant or unbelievable" , "Super!" , "Splendid, excellent" .)
