Etymology: Cognate comes from Latin "cognatus," literally "related by blood," built from "co-" (together) and "gnatus," "born." The Latin root "gnatus" is also the source of words like "natal" and "nation," which means the Latin family of ideas has always been about birth and kinship. Latin speakers used "cognatus" for relatives on the mother's side, which gives the word its original family flavour. English borrowed the term directly from Latin, and it has long carried that sense of shared descent. Over time it spread from describing blood relatives to describing words: a cognate is a word in one language that descends from the same ancestral word as a word in another, such as English "father" and Latin "pater." The shift from people to vocabulary mirrors how linguists began treating languages as family trees. "Connate" is a close doublet, meaning the same Latin ancestry arrived in English by a different route, and it is sometimes used for things born together or existing from the beginning.
