The adjective, determiner, and noun are derived from Middle English leste, lest, last (“(adjective) smallest, least; (noun) smallest thing, etc.; person or thing least in importance; etc.”), from Old English lǣst, a contraction of læsast, læsest (“least”) (also lærest in only one source), from Proto-Germanic *laisistaz (“smallest, least”), from *laisiz (“less”) (possibly from Proto-Indo-European *leh₂is- or *leh₃is-; whence modern English less) + *-istaz (“suffix forming superlative forms of some adjectives”). The adverb and pronoun are derived from the adjective or determiner. cognates * Old Frisian leist * Old Saxon lēs
