Etymologically, the entry records: From French pessimisme, from Latin pessimus (“worst”) + -ism, superlative of malus (“bad”). As a doctrine, from German Pessimismus as used by the German philosopher Arthur Schopenhauer in 1819. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is pessimism, spelled P-E-S-S-I-M-I-S-M, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
