Altruism Has Roots in Latin and French

Altruism refers to a quality possessed by people whose focus is on something other than themselves, and its root reveals the object of those generous tendencies. Altruism derives from the French word autrui, meaning "other people." Autrui, in turn, developed from the Old French term autre, which means "other" and which itself comes from Latin alter, also meaning "other." That Latin source eventually caused a curious thing to happen. Under the influence of alter, the French autrui gave rise to the altrui- of both the French altruisme and the English altruism. The English term has been in service since at least the mid-1800s.
