Pronunciation

  • 12th century Icelandic: /ˈfɑðɪr/[1]

Forms

faðir m (genitive fǫður, plural feðr) (strong r-stem)[1] Runic faþiR on the Rök stone[2] and accusative foþur on the Norwegian stone N 273.[3]

Etymology

It is inherited from Proto-Germanic *fadēr (“father”),[4][1] which gave Gothic 𐍆𐌰𐌳𐌰𐍂 (fadar), Old English fæder, Old Frisian feder, Old Saxon fadar and Old High German fater.[4][5] It is the Indo-European word for “father”, Proto-Indo-European *ph₂tḗr, a ter-stem, the source also of Latin pater, Ancient Greek πατήρ (patḗr), Old Irish athir, Tocharian A pācar and Tocharian B pācer.[4][5]

Hellquist and Falk and Torp derive the word from the nursery word ⟨pa⟩ with the suffix *-ter- of kinship terms.[6][7] Ásgeir Blöndal Magnússon mentions this view and another, from a root *pō(i)-, *pā- “to protect”, and calls both doubtful.[8] De Vries cites Trier's argument that the word was a legal term for the head of the family rather than a biological one.[9]

Earliest recorded meaning

The Rök stone, which Rundata dates to the 800s, has the word in its opening lines: En Varinn fáði, faðir, ept feigjan son “And Varinn, the father, coloured (the runes) in memory of his dead son”.[2][10] The Norwegian stones use it in the memorial formula, as on N 273 of 980–1015: Þormóðr reisti stein þenna eptir Þormóð … fǫður sinn “Þormóðr raised this stone in memory of Þormóðr …, his father”.[3][11]

Semantic evolution

Besides the natural father, ONP separates the man named or recognised as a child's father, God as father of Jesus, God as the Father in the Trinity, and God as father of all Christians.[12] The plural feðr was used of the Church Fathers from the first manuscripts on,[12] and Ásgeir Blöndal Magnússon adds the senses “originator” and a form of address for Catholic clergy.[8] In poetry the word forms kennings, such as faðir galdrs for Óðinn.[13] More than a third of ONP's citations are from legal texts, far more than expected.[12]

It continues as Icelandic faðir and Faroese faðir, and as Swedish fader and Danish fader, with the short forms Swedish far and Danish far.[9][6]
