Grammar error for Aetheryte tutorial NPCs

So I believe back in 2014, the NPC Nicia was mentioned as giving incorrect dialogue regarding aetheryte travel however, I spotted something today that just seemed a bit unusual.


This is her question menu when you interact with her.

The middle question's grammar is very "odd".
I went and checked the other Aetheryte NPCs in Limsa Lominsa and, oddly enough - Sundhimal in Limsa Lominsa also shares this menu but Nenebaru in Ul'dah actually has this menu instead.

"What are aetherytes?" certainly reads a lot better than "What is aetheryte?".. which calls to mind a certain vine.
