Ultima thule is a noun that refers to a distant, unknown region.
Our word of the day is a combination of the Latin word Ultima (OOL team uh) which means ‘final’ and thula, a word of Greek origin that refers to ‘the northernmost region of the world.’
Ultima Thule does not refer to a specific location. It simply means any unknown, distant place. For example: When we found ourselves lost in the jungle, we were afraid we’d wind up in some distant place we wouldn’t be able to identify. But instead of finding some dangerous Ultima Thule we somehow made it back home.
