ruby: [14] Ruby goes back ultimately to Latin ruber ‘red’, a descendant of the same Indo- European base as produced English red. From it was derived the medieval Latin adjective rubīnus, which was used in the term lapis rubīnus ‘red stone’. In due course rubīnus itself came to be employed as a noun in this sense, and it passed into English via Old French rubi. Other English words from the same source include rubella [19], rubicund [16], rubidium [19], and rubric [14] (headings in ancient and medieval manuscripts were often written in red ink). => red, rubella, rubicund, rubric
ruby (n.)
"clear rich-red variety of corundum," c. 1300, from Old French rubi (12c.), from Medieval Latin rubinus lapis "red stone" (source also of Italian rubino), from Latin rubeus "red," related to ruber (see red). As a color name from 1570s. As an adjective from late 15c. Modern French rubis is not explained; Klein suggests a plural mistaken for singular.
