Forms

þekkja weak verb (past tense þekkta, past participle þekktr; an older past tense þátti in poetry)[1][2] Faulkes also gives the past tense þekði and the participle þekðr.[3] Old Norwegian manuscripts write þecte,[4] þæcti and þæckiaz.[5]

Etymology

It is inherited from Proto-Germanic *þankijaną (“to perceive, to think”),[6] the verb Köbler writes *þankjan.[7] The same verb is Gothic 𐌸𐌰𐌲𐌺𐌾𐌰𐌽 (þagkjan, “to think”), Old English þencan, Old Frisian thenza, Old Saxon thenkian and Old High German denken, all meaning “to think”.[8][9][7]

Outside Germanic the only certain relative is Old Latin tongeō (“to know”), with an Oscan noun beside it, so the word is found only in Italic and Germanic.[8] Köbler and Pokorny's dictionary put both under a root *tong-, *teng- “to think, to feel”.[7][10] Wiktionary takes the Germanic verb to be a causative Proto-Indo-European *tong-éye-ti of Proto-Indo-European *teng- (“to think, perceive”).[6]

Cleasby and Vigfússon note that Old Norse kept the sense “perceive, know” and never developed “think”, which entered later with the borrowed form þenkja.[2] De Vries and Köbler list separately the sense “to make pleasant”, with a middle voice meaning “to be pleasing, to accept”, which belongs with the adjective þekkr “pleasant”;[8][11] Zoëga and Fritzner treat these senses under one verb.[1][12]

Earliest recorded meaning

IcePaHC finds the verb first in the Icelandic Homily Book, which it dates to 1150, in the forms þekkjum, þekkt and þekkjanda.[13] Menota's earliest dated manuscript with it is the Norwegian AM 619 4to of 1200–1225, with the past tense þecte.[4] The oldest sense is “to notice, to catch sight of”: in an Eddic poem þás bani Fáfnis borg of þátti “when Fáfnir's slayer caught sight of the stronghold”, with the old past tense.[1][14]

Semantic evolution

The senses run from noticing with the senses to understanding and then to knowing and recognising a person or thing.[1][12] Cleasby and Vigfússon describe “to perceive, espy” as obsolete in modern Icelandic, where “to know” is the sense left.[2] In the poems the old past tense þátti is used of seeing something,[15] and Finnur Jónsson lists in skaldic verse a verb þekkja “to chastise” and the middle þekkjask “to be content with”.[16] The middle þekkjask “to accept, to be pleased with” is common in the sagas, as in Gunnsteinn þektist boð þat “Gunnsteinn accepted that offer”.[12][17]

The verb continues as Icelandic þekkja “to know”, with the noun þekking “knowledge” made from it, and as Faroese tekkja and Norwegian Nynorsk tekkja.[9][18]
