From Middle English erthe, from Old English eorþe, from Proto-West Germanic *erþu, from Proto-Germanic *erþō (compare Western Frisian ierde, Low German Eerd, Dutch aarde, nds-nl eerde, German Erde, Danish -, Swedish - and Norwegian jord), related to *erwô ("earth") (compare Old High German ero, perhaps Old Norse jǫrfi), from Proto-Indo-European *h₁er- (compare Ancient Greek *ἔρα, “earth” in ἔραζε ("to the ground, to earth"), perhaps Tocharian B yare.

Probably unrelated, and of unknown etymology, is Old Armenian երկիր (erkir, “earth”). Likewise, the phonologically similar sem-pro *ʔarṣ́- – whence Arabic أَرْض (ʔarḍ), Hebrew אֶרֶץ (ʾereṣ) – is probably not related.
