I've had the name for years...it's a bastardization of the world for "earth" in either Gaelic or Sindarin; I can't remember which; I bastardize both a lot because they make for good-sounding fantasy names with a touch of realism behind them. I'm probably going to add Finnish to that list as well, because it's a beautiful-sounding language. And the reason I bastardize is so that people who are native speakers of Gaelic or Finnish (when I start messing with it) don't go, "oh, gee. His world is called 'Earth.' How clever."Hey, where'd you come up with the name "Domaria"? Reason I ask is my homebrew setting is named Domibia, which is close to "Domaria". (It's also the name under which I started my first publishing endeavor, pre-Seraphim Guard.)
"Domibia" comes from the Latin "Domus" ("home") and Ibi ("place"). Thus Domibia is our "home place".
