trust

英文词源

trust

trust: [13] Trust was probably borrowed from Old Norse traust ‘help, confidence, firmness’. This, together with its modern German and Dutch relatives trost and troost ‘consolation’, goes back to the same prehistoric Germanic base as produced English true and truth. Tryst [14] is probably closely related. It was borrowed from Old French triste ‘appointed place for positioning oneself during a hunt’, which itself was very likely acquired from a Scandinavian source connected with traust.
