As far as I know there are a few things that have names .. examples being the Irifon river, the river that you cross to go to Ojaveda. Just before that you have the Korogan pass, which is the tunnel that connects Ojaroad1 with Ojaroad2. Then there are of course the city sections: East Hydlaa, Upper Hydlaa, Hydlaa Plaza and the Ojaveda merchant district & Ojaveda warehouse district with the Utlics (tent camps) and last but not least the Bronze Doors Fortress.
Most of the other areas have been given less original names like the Ruins, the Stone Face, the Bronze Doors mine and the Magic Shop.
If you take time to talk to NPC's or read some books at Jayose (not sure if those books are back already though) you'd be surprised what you can learn.
P.S.: If I'm mistaken with anything or forgot something please correct me or add things
