Etymology: Its root is Latin "ruber," meaning red. The same root gives us "ruby," through Old French "rubis," and "rubric," which originally named red ochre, the red earth used to mark titles and headings in manuscripts. That is why rubrics were the red-inked lines set apart from the black text. The Latin verb "rubefacere" combines "ruber" with "facere," to make, so it literally means "to make red." The noun "rubefactio" names the act of doing so. English medicine kept the Latin form, and the related "rubefacient" describes substances, such as mustard plasters and certain liniments, that redden the skin and draw blood toward the surface.
