Word History

Etymology

borrowed from French pessimisme, from Latin pessimus "worst" + French -isme -ism, formed by analogy with optimisme optimism; Latin pessimus, probably going back to *pedisamos, derivative (with -isamos, superlative suffix, going back to Italic & Celtic *-ism̥mos) of *ped-, extracted from *ped-tu- "a fall, falling" (whence Latin pessum "to the bottom, to destruction"), verbal noun from an Indo-European base *ped- "step, fall," whence, with varying ablaut grades, Old English gefetan "to fall," Old Church Slavic padǫ, pasti, Sanskrit padyate "(s/he) falls, perishes"

Note: The Indo-European verbal base *ped- is generally taken to be a derivative of the noun *pōd-, ped- "foot"; see foot entry 1.
