Origin & History of “red”
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’ (19th c.)) and a whole range of Latin ‘red’-words, including ruber (source of English rubicund and ruby), rubeus (source of English rouge (15th c.)), russus (source of English rissole and russet), and rūfus (source of English rufous (18th c.)). 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.
