A lot of the spell names came from earlier FF titles where word length was a consideration, but unfortunately those limitations have frequently been reinforced by translators who should know better. And a lot of mistakes have been adopted officially when they should not have been. It's kind of like a load of school children all taking a math exam, and all of them getting the same question wrong, so the exam board decide to make the mistake the correct answer. And then when someone comes along and points out it's wrong, they get pounced on like they're some destroyer of the greater good.
You may have a point with null being at the end. What do you think, Covarr?
Actually, yeah, I think Null at the start may be better English.
