Forms

gewiss (strong nominative masculine singular gewisser, comparative gewisser, superlative am gewissesten)[1] The older spelling is gewiß.[1]

Etymology

It is inherited from Middle High German gewis, inherited from Old High German giwis, inherited from Proto-Germanic *gawissaz (“known, certain”).[2][1][3] The same word is Gothic 𐌿𐌽𐍅𐌹𐍃𐍃 (unwiss, “uncertain”), Old Norse víss, Old English gewis and Old Frisian wiss, and today Dutch gewis and Swedish viss.[2][1] It is an old to-participle of the verb now wissen, so it properly meant “known”.[2][4] The participle goes back to Proto-Indo-European *u̯ei̯d- (“to see”), through a form Proto-Indo-European *u̯id-to- (“seen”) in which the meeting dentals gave -ss-; Sanskrit वित्त (vittá, “known”) corresponds exactly.[3][4][5] The verb has since formed a new participle, gewusst.[4]

Earliest recorded meaning

Old High German giwis is recorded from the end of the 8th century in glosses, and then in the Benedictine Rule, the Murbach Hymns, Otfrid and Notker, meaning “certain, sure, fixed, true, reliable”.[3][6]

Semantic evolution

From “what is known” the word came to mean “what is surely known”, and then “certain, sure”.[4] The Grimms' dictionary points out that while weise, from the same root, took an active sense (“knowing”), gewiss kept a passive one (“known”).[5] The adverb (gewiss! “certainly”) is attested in Middle High German, about 1185 in Hartmann's Erec.[7] In the modern language the adjective also means “certain, some”, of something not named more precisely (ein gewisser Herr Krause).[8]

Timeline

  • 1077–1081 – Middle High German gewis is used in the Annolied.[7]

  • 17th century – vergewissern “to make sure” is formed.[4][10]
