Forms
þak n (genitive þaks, plural þǫk) (strong a-stem)[1]
Etymology
It is inherited from Proto-Germanic *þaką (“roof, cover”),[1][2] the noun behind Old English þæc (“roof”), Old Saxon thak and Old High German dah (“roof, covering”).[2][3] Köbler sets up the Germanic stem as *þaka-.[4]
Orel, Ásgeir Blöndal Magnússon and Hellquist relate it to Latin toga (“covering, garment”) and tegō (“to cover”), Old Irish tech (“house”), Ancient Greek τέγος (tégos, “roof”) and Lithuanian stógas (“roof”), all from the root Proto-Indo-European *(s)teg- (“to cover”).[2][5][6] Within Old Norse the verb þekja (“to thatch, cover”) and the adjective þjokkr (“thick”) belong to the same group,[7][4] and so does þaka (“turf used for roofing”).[5]
Earliest recorded meaning
The first dated record is in the manuscript Holm perg 34 4to, of 1276–1300, where þak occurs twice.[8] Fritzner cites the word from the Norwegian law (Landsl. 7, 28) and thinks it may there mean birch bark for roofing, though it may equally stand for þakviðr “roofing timber”.[9] The Eddic poem Guðrúnarkviða III has the older sense “cover”: at it Þjóþrekr und þake svæfeþ “that you and Þjóðrekr slept under one cover”.[10][11]
Semantic evolution
The word first named any covering: Zoëga and Fritzner put the bed-cover of the Eddic line first, and the roof second.[12][9] In prose the usual sense is the roof of a house, made of turf, wood or shingles, as in the compounds torfþak, timbrþak and spánþak.[13] From the roof the word passed to the material laid on it, especially birch bark in Norwegian charters.[9][14] In the law of Grágás it stands for baugþak, an additional payment.[13][9][7]
The word continues as Icelandic þak (“roof”),[5][15] Swedish tak and Danish tag.[6] De Vries also notes a loan into Shetland dialect, tag, and into Sami as dakke, takka.[7]
