Forms

froða f (genitive froðu)[1]

Etymology

It is inherited from Proto-Germanic *fruþō (“foam”),[2] a weak noun beside the strong frauð (“froth”).[3][4] Old English has the related verb Old English āfrēoþan (“to froth”).[5][6] Ásgeir Blöndal Magnússon and Holthausen compare a Sanskrit verb meaning “to snort, blow”, and Köbler places the family under Proto-Indo-European *preut- (“to spray, snort”).[6][5][7]

Ásgeir Blöndal Magnússon sees the original sense “blow” preserved in Norwegian Nynorsk froe (“gust of wind”), and connects freyða (“to foam”).[6]

Earliest recorded meaning

ONP's first dated record is in Maríu saga, in a manuscript of 1350: Þá setti út froðu mikla um munninn “Then a great deal of froth came out round the mouth”.[8] The record of 1362 also has foam at the mouth, of wild boars: spyta þeir af munnínvm frodu af mædinne “they spit froth from their mouths from exhaustion”.[8]

Semantic evolution

ONP gives froth, foam and mucus as the main sense and, in three records, semen as a bodily fluid.[8] Baetke glosses it “foam, slaver”, and most records are in religious texts and romances.[9][8] In later Icelandic it is frequent, with compounds such as froðufall “foaming at the mouth”.[1]

The word continues as Icelandic froða, Faroese froða, Norwegian Nynorsk frode and Danish fråde.[6][3] De Vries, after Björkman, takes Middle English froþe, English froth, from the Norse word;[3] Etymonline derives it from an unrecorded Old English word or from Old Norse.[10]
