cloudとは 意味・読み方・使い方

語源

From Middle English cloud, from 古期英語 clūd (“mass of stone, rock, boulder, hill”), from Proto-Germanic *klūtaz, *klutaz (“lump, mass, conglomeration”), from Proto-Indo-European *gel- (“to ball up, clench”).

Cognate with Scots clood, clud (“cloud”), Dutch kluit (“lump, mass, clod”), German Low German Kluut, Kluute (“lump, mass, ball”), German Kloß (“lump, ball, dumpling”), Danish klode (“sphere, orb, planet”), Swedish klot (“sphere, orb, ball, globe”), Icelandic klót (“knob on a sword's hilt”). Related to English clod, clot, clump, club. Largely replaced Middle English wolken, from 古期英語 wolcn (whence Modern English welkin), the commonest Germanic word (compare Dutch wolk, German Wolke).
