bók f (genitive bókar or bǿkr, plural bǿkr) (strong consonant stem)[1]
Etymology
The word for the book is inherited from Proto-Germanic *bōks (“tablet of beechwood, book”).[2][1] The same noun is Gothic 𐌱𐍉𐌺𐌰 (bōka), plural “letter, book”, Old Saxon bōk (“writing tablet”), Old Frisian bōk, Old English bōc and Old High German buoh.[3][4]
Most etymologists take it to be the same word as bók2 “beech”.[5][4][6] Cleasby and Vigfússon thought the identity certain and noted that bókstafr properly means a beech twig;[5] Falk and Torp, Torp and Jóhannesson explain the book as a tablet of beechwood with runes carved in it, used at first in the plural.[4][3][7] Ásgeir Blöndal Magnússon likewise thinks of thin beech boards to scratch on, the book being named after its material as Ancient Greek βίβλος (bíblos) and Latin liber (“book; bast”) were.[6]
The Norse sense “book”, however, is held to come from Old English. Ásgeir Blöndal Magnússon thinks it probably came from bōc with Christianity and clerical learning,[6] Jóhannesson calls it a semantic loan from the Old English word,[7] and de Vries describes the inherited word as reshaped in meaning by it.[8] De Vries adds that a tablet of beechwood suits the word badly, since it names the foreign written book; he reports H. Kuhn's link with Proto-Germanic *baukna- (compare bákn), through “mark, sign” to “written letter”, and H. Rosenfeld's view of an early borrowing for the beechwood wax tablets used for letters.[8] Ásgeir Blöndal Magnússon thinks the link with ⟨bákn⟩ unlikely.[6]
Earliest recorded meaning
The earliest dated record in Menota is the plural bǿkr in the fragment NRA norr fragm 81 A, dated 1150–1250.[9] ONP's citations of 1200 already show the sense “book” itself: En þa es líþr líf þetta ... eige þarf þa bóc at lesa “But when this life passes ... then there is no need to read the book”.[10]
Semantic evolution
From the book as an object the word came to name a literary work, a volume of a longer work and, often in the plural, the older written authorities;[10] heilǫg bók was Holy Scripture.[10] The book on which oaths were sworn, the Bible or the Gospels, gave phrases such as vinna eið at bók “to swear an oath on the book”.[10][11] The book also stood for learning and for Latin: kenna á bók “to teach to read”, nema á bók “to study”, setja til bǿkr “to put to study”, kunna á bók “to know Latin”.[10][12] In Norway the book was above all the law code: Hertzberg's Norwegian laws use it of the lǫgbók,[13] and Zoëga names the codes lögbók and Jónsbók.[12] In the legal texts the word is more frequent than ONP's genre table expects.[10]
In a few Eddic poems bók is an embroidered or figured cloth, a bed cover: bǿkr þínar inar bláhvítu “your blue-white covers”.[14][15] Cleasby and Vigfússon took this for the earliest Scandinavian sense of the word,[5] and de Vries lists it under the book word.[8] Finnur Jónsson explains it from the thin beechwood slats used in weaving,[16] while Fischer counts it among the meanings borrowed in the Eddic poems.[17]
The word continues as Icelandic bók, Faroese bók, Norwegian bok, Swedish bok and Danish bog.[6][4]

Etymology
The word for the beech is inherited from Proto-Germanic *bōkō (“beech”).[1][2] It matches Old English bēce, Old Saxon bōk, Middle Low German bōke and Old High German buohha.[8][21] Outside Germanic it answers to Latin fāgus (“beech”), which agrees in meaning, and to Ancient Greek φηγός (phēgós, “a kind of oak”).[8][6] Pokorny's root is Proto-Indo-European *bʰāgós (“beech”).[2]
De Vries and Hellquist mention the usual link with Ancient Greek φαγεῖν (phageîn, “to eat”), which would make it the tree with edible fruit.[8][21] Ásgeir Blöndal Magnússon calls the further origin uncertain, as is which tree the word first named, and mentions a comparison with Kurdish and Russian names of the elm and the elder,[6] which Hellquist thinks surely wrong.[21] De Vries notes that the modern words Icelandic baukr (“box”) and Icelandic beyki (“beech”) point to a Germanic alternation of two vowel grades.[8]
Earliest recorded meaning
The tree is rare in the record: Cleasby and Vigfússon explain that Iceland had no beeches, and that the collective beyki is the more frequent word.[5] Bók “beech” stands in the þulur, the lists of poetic names.[16][11] ONP labels the word poetic and has one dated citation, from a boundary description of 1312: j sundit vidr Haugin ok Bokena “into the sound by the mound and the beech”.[10]

- 1312 – Bokena in a boundary description cited by ONP under the poetic bók “beech”.[10]
