Etymology
Comes from Latin tellūs (“earth, ground; the globe, planet Earth; country, land”), ultimately from Proto-Indo-European *telh₂- (“ground, bottom”), plus -ian (a suffix meaning “from, related to, or like” when forming an adjective, or “one from, belonging to, relating to, or like” when forming a noun).
