hoard [hoard 词源字典]: hoard: [OE] Etymologically, a hoard is ‘that which one hides’. The word comes from a prehistoric Germanic *khuzdam, which was derived from the same base as the verb hide. (Hoarding [19], incidentally, is not etymologically connected; it comes from an earlier hoard ‘fence’, which probably goes back via Old French hourd or hord to a prehistoric German form that also produced English hurdle [OE]. Nor is the identically pronounced horde [16] related: it goes back via Polish horda to Turkish ordū ‘camp’, source also of Urdu [18], etymologically the ‘language of the camp’.)
