What's the meaning of the spell's name that Wendy uses to cure Natsu's vehicle-sickness? In chapter 152 Wendy cures Natsu's sickness for vehicles. When doing this enchantment/spell she says TROIA:



What does that mean? Is it just a random word?

I ask this because troia is the Italian word for whore, but I hope it isn't related to this.  I'm reading the manga in English, so that's not an Italian translation.
This is probably just a random word created by the mangaka for the spell's name. It's probably just a coincidence that Troia meant whore in Italian translation. After all, it's a healing magic so it won't make sense that the mangaka chose that kind of word intentionally if knew that meaning in Italian translation. You can find Troia's full description here.
