YOU SAID:
Simone is one of, if not the most terrible person in the world
INTO JAPANESE
シモーネは、世界で最も恐ろしい人ではないにしても
BACK INTO ENGLISH
Simone is not the scariest person in the world
INTO JAPANESE
シモーヌは世界で最も怖い人ではありません
BACK INTO ENGLISH
Simone is not the scariest person in the world
That didn't even make that much sense in English.
