Forms
svefn m (strong a-stem)[1] Early Norwegian manuscripts also write søfn, sœmn and semn (dative semnenom), and a medieval Bergen rune stick has suæfn.[2][3][4]
Etymology
It is inherited from Proto-Germanic *swefnaz (“sleep”),[1][5] the Proto-Germanic noun also continued in Old English swefn (“sleep; dream”) and Old Saxon sweƀan.[5][6] It goes back to Proto-Indo-European *swépnos (“sleep”), an extension of *swep- (“to sleep”),[1] the source also of Latin somnus, Ancient Greek ὕπνος (húpnos), Old Irish suan and Latvian sapnis (“dream”).[1][7]
Kroonen notes that the Germanic word shows no effect of Kluge's law, which points to stress on the root as in Sanskrit; he compares Latin sopor (“deep sleep”) as a related formation.[5] Ásgeir Blöndal Magnússon suggests that the Indo-European forms grew out of an old heteroclitic paradigm with a nominative in *-ōr and an oblique stem *supn-.[8] De Vries reports Benveniste's view that the root is an extension of an older root seen in Greek words for sleeping.[7]
The noun is related to the verb sofa (“to sleep”).[7][9] Hellquist holds that the East Norse forms, Old Swedish sømn and its relatives, are not a regular outcome of the Germanic stem but a reshaping of it.[10]
Earliest recorded meaning
IcePaHC dates its first record to 1150, in the Icelandic Homily Book, where it means “sleep”;[11] Larsson lists svefn, svefni and svefns from the same manuscript among the oldest Icelandic ones.[12] The Norwegian Homily Book (AM 619 4to, 1200–1225) has the variants svefne, søfne and semnenom.[2] A medieval rune stick from Bergen, which Menota dates within 1100–1500, opens Svefn bannar mér “sleep forbids me”, that is, “I cannot sleep”.[13][4]
Semantic evolution
The second sense, “dream”, stands beside “sleep” in the poetry: Lexicon Poeticum gives segja slíkan svefn “tell such a dream” in Atlamál, and phrases such as e-m berr í svefn “something appears to one in sleep”.[14] Ásgeir Blöndal Magnússon notes that the word means “dream” in many Germanic and Indo-European languages, as Latin somnium does beside somnus.[8] Fritzner points to a passage where svefn is used just like draumr “dream”.[15] In Icelandic the sense “dream” is now obsolete.[8]
In the language of war, Hertzberg records svefn as the name of a small troop that formed a fellowship on campaign and fought as a unit.[16] The word continues as Icelandic svefn, Faroese svøvnur, Norwegian Nynorsk svevn, Swedish sömn and Danish søvn.[7][8]
