least

Pronunciation

• IPA: /liːst/^[1]

Etymology

It is inherited from Middle English leest, inherited from Old English lǣst, a contraction of earlier lǣsest (“smallest”),^[2][3][4][5] from Proto-Germanic *laisistaz,^[3][4] the superlative formed on the same base as less.^[4][5][6] Etymonline traces it to Proto-Indo-European *leis- (“small”).^[2][7] It serves as the superlative of little,^[2][8] but Chambers points out that, like less, it has no positive of its own.^[9] Its counterpart in Old Frisian is lērest (“least”).^[10]

Earliest recorded meaning

Smallest, lowest in power or position: Old English lǣst, before 950,^[3][2] also used as an adverb, “in the least degree”.^[2]

Semantic evolution

As a noun it meant “the least important person” about 1125,^[3] and “the smallest admissible amount” in the early 12th century.^[2] At least “not to say more than is certainly true” goes back to Middle English æt læstan, “at the lowest degree”.^[2] The Middle English adjective appears probably before 1200 in the Ancrene Riwle.^[3] From 1597 least has been used in the names of the smallest species of a group of plants or animals.^[11] Colloquially it can also mean “fewest”.^[5] Leastways and leastwise are formed from it.^[4][6]
