The word optimism emerged in the 18th century from French optimisme, coined by philosopher Leibniz to describe his belief that the world is the "best possible" creation. It combines optimum (Latin for "best") with -ism, reflecting a philosophical stance. The root optim retains its core meaning of "best," while -ism generalizes it into a worldview.
