In some game, the narrator said:
"Great is the weapon that cuts on its own"
I can't get it, how could this clause be grammatically right, the issue is in the part "Great is the", to me that means that what follows is the definition of "great", which is not only not the desired meaning, it also has no right meaning, "Greatness" had to be used in this case, but for the desired meaning, it should be something like "Great it's the weapon that cuts on its own", just adding "it" after the word "Great" would solve this issue for me.
