The story of "cognate" is all relative: that is, it's all about relatives. Cognate words share an ancestor, like "allude" and "prelude" (which both trace to the Latin root ludere) and the English "brother" and the German Bruder (which are both related to the Greek phrater). Cognate languages, like French, Spanish, and Italian, descend from the same ancestral language. People related through a common ancestor are cognate, and groups of people, such as tribes, can be cognate to one another. "Cognate" also describes things related in a more figurative way, as in "cognate developments," "cognate disciplines," or "cognate problems." "Cognate" itself comes from the Latin cognatus which traces to Latin nasci meaning "to be born." Some words cognate to "cognate" include "innate," "nascent," "native," and "Renaissance."
