Etymology

Origin of consanguineous

First recorded in 1595–1605; from Latin consanguineus “related by blood, kindred; blood relation, kinsman,” equivalent to con- + sanguin- (stem of sanguis) “blood” + -eus adjective suffix. Consanguineous first occurs in Shakespeare's Twelfth Night (1602), and Shakespeare may have introduced the word into English. See con-, -eous

Explanation

To be consanguineous is to be related by blood. A mother and her biological child are consanguineous. Consanguineous comes from a Latin word meaning "of the same blood," and that's exactly what this word means. This word applies to everyone who is a blood relation: a mother and father are not consanguineous, but they are both consanguineous with their biological children. All the puppies or kittens in a litter are consanguineous. First cousins are consanguineous. An adopted child will not be consanguineous with anyone in his or her adoptive family.
