earth.とは 意味・読み方・使い方

語源

From Middle English erthe, from 古期英語 eorþe, from Proto-West Germanic *erþu, from Proto-Germanic *erþō (“dirt, ground, earth”) (compare West Frisian ierde, Low German Eerd, Dutch aarde, Dutch Low Saxon eerde, German Erde, Danish, Swedish かつ Norwegian jord), related to *erwô (“earth”) (compare Old High German ero, perhaps Old Norse jǫrfi), from Proto-Indo-European *h₁er- (compare Ancient Greek *ἔρα (*éra) in ἔραζε (éraze, “on the ground”), perhaps Tocharian B yare (“gravel”).

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