different between earth vs diatomite

English

Etymology

From Middle English erthe, from Old English eorþe (“earth, ground, soil, dry land”), from Proto-West Germanic *erþu, from Proto-Germanic *erþ? (“earth, ground, soil”) (compare West Frisian ierde, Low German Eerd, Dutch aarde, Dutch Low Saxon eerde, German Erde, Danish, Swedish and Norwegian jord), related to *erwô (“earth”) (compare Old High German ero, perhaps Old Norse j?rfi), from Proto-Indo-European *h?er- (compare Ancient Greek *??? (*éra) in ????? (éraze, “on the ground”), perhaps Tocharian B yare (“gravel”).

Probably unrelated, and of unknown etymology, is Old Armenian ????? (erkir, “earth”). Likewise, the phonologically similar Proto-Semitic *?ar??- – whence Arabic ?????? (?ar?), Hebrew ?????? (?ere?) – is probably not related.
