red [red 词源字典]: red: [OE] Red is an ancient colour-term, whose history can be traced back to prehistoric Indo- European *reudh-. This also produced Greek eruthrós ‘red’ (source of English erythrocyte ‘red blood cell’ [19]) and a whole range of Latin ‘red’-words, including ruber (source of English rubicund and ruby), rubeus (source of English rouge [15]), russus (source of English rissole and russet), and rūfus (source of English rufous [18]).

Amongst other English words from the same Indo-European source are robust, ruby, ruddy [OE], and rust. The immediate Germanic precursor of red was *rauthaz, which also produced German rot, Dutch rood, Swedish röd, and Danish rød.
