trustとは 意味・読み方・使い方

語源

From 中期英語 trust, trost (“trust, protection”). Long considered a borrowing from Old Norse traust (“confidence, help, protection”), from Proto-Germanic *traustą, but the root vocalism is incompatible, so trust has come to be considered a reflex of an unattested 古期英語 *trust, from a rare zero-grade Proto-Germanic variant of the same root also attested in Middle High German getrüste (“host”). Ultimately from Proto-Indo-European *deru- (“be firm, hard, solid”). Akin to Danish trøst (“comfort, solace”), Saterland Frisian Traast (“comfort, solace”), West Frisian treast (“comfort, solace”), Dutch troost (“comfort, consolation”), German Trost (“comfort, consolation”), Gothic trausti (“alliance, pact”). Doublet of tryst. More at true, tree.
