Etymology / origin

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