Etymology: "Pessimus" is the Latin superlative of "malus" (bad), built on the irregular stem "pess-" that Latin used in place of "malus" in its comparative and superlative forms. The comparative was "pejor" (worse) and the superlative "pessimus" (worst), so the same root supplies the English "pejorative" and "pessimism" through the comparative and superlative forms. The root "pess-" is thought to be related to "pejor" and to an older form connected with "peius" and "pessum," meaning "to the bad" or "downward," though the exact internal history of the stem is not fully settled. English "pessimism" was formed in the 18th century from Latin "pessimus," and "pessimist" followed in the early 1800s, when writers adopted the Latin superlative as a philosophical label for the view that the world is as bad as it can be. Its opposite, "optimus" (best), gave "optimism" by the same route, and the two were coined as a pair. So the word you have here, in its Latin form, is the source of an English philosophical vocabulary rather than an English word itself.
