Etymology

It is inherited from Middle High German kein, a shortening of nekein and enkein, inherited from Old High German nihein, inherited from Proto-West Germanic *nehwain, originally “and not one”.[2][1][4] The Old High German pronoun joins the numeral ein (“one”) to a conjunction Proto-Germanic *nehw (“and not, nor”), made of the negation Proto-Indo-European *né and Proto-Indo-European *-kʷe (“and”); it matches Latin neque and Oscan nep.[5][4][1] Old High German had the variants nohein (8th century), nihhein (9th century) and nehein (around 1000).[5] The same word is Old Saxon nigēn, Middle Low German gēn, Old Frisian gēn, Dutch geen and Yiddish קיין (keyn);[2][5][4][1] Kluge explains their ⟨g⟩ by weak sentence stress, Pfeifer by grammatical change.[2][5][4][1]

The modern form arose when the syllable-initial ⟨ch⟩ of nechein hardened to ⟨k⟩.[2][6] But the Middle High German word also meant “any”, the sense of dehein, thehhein, whose first part is of unclear origin.[2][7] The sources therefore see the modern word as a blend of both pronouns: the Duden, Paul and the Frühneuhochdeutsches Wörterbuch derive it from a mixture of “not one” and “any”.[7][6][8] Behaghel derived it from ⟨dehein⟩ alone, and the Althochdeutsches Wörterbuch also takes chein as a shortening of ⟨thehein⟩ rather than of ⟨nehein⟩.[5][9]

Earliest recorded meaning

Old High German nihein “no, none, nobody” is common from the beginning of the 9th century in glosses, the Tatian, Otfrid, Notker and other texts.[4][10] The form chein first appears in the second half of the 11th century, in Williram of Ebersberg and in Otloh's prayer (after 1067), meaning “any”.[5][4][11]

Semantic evolution

In Middle High German, sentences with a double negation often dropped the negative particle, so dehein “any” could itself mean “no”; around 1200 this began the decline of nehein, whose variant enkein last appears in the 16th century and survives in Swiss dialect nekein.[5][4] Kein, usual from the end of the 12th century, had both senses, “no” and “any”, into the 16th century.[5][8] Paul quotes Wolfram's ie ze keiner stunt “at any hour” and Luther's tiefer denn kein Abgrund “deeper than any abyss”, and the sense lingers after comparatives into the 18th century: Goethe has mehr als kein anderer Geist “more than any other mind”.[6]

Derivatives built on adverbial genitives followed: keinerlei “no kind of” (14th century), keineswegs “by no means” (late Middle High German deheins wegs, 14th century; written as one word from the 16th) and keinesfalls “in no case” (first half of the 19th century).[5][7]
