Did you know?

Consanguineous is part of a family of "blood" relatives that all descend from the Latin noun sanguis, meaning "blood." Some of these relatives are found on the literal branch of the family tree, as "exsanguination," a term for the draining or removal of blood. Others are on the figurative side of the family, such as "sanguine," a word that can mean "bloodred" or "ruddy" but that is more often used with the meaning "cheerful" or "optimistic." There is also "sangfroid," a French word (literally meaning "cold blood") that was borrowed into English to refer to self-control under stress. "Consanguineous" relies on the "kinship" sense of "blood," bringing together "sanguis" with the Latin prefix con-, meaning "with," to form a word used to describe two or more organisms that descend from the same ancestor.
