faðr

Faðr is a historical noun meaning "father" in Old Norse and related early Germanic languages, written with the letter ð (eth). It appears in scholarly references and historical texts as an older form of the word that later evolved in the Scandinavian languages. In contemporary Icelandic, the standard word for "father" is faðir, with faðr seen mainly in etymological descriptions and older sources.

Etymology and relatives: The word is descended from Proto-Germanic *fadēr, which in turn comes from the Proto-Indo-European root *ph₂tḗr, the common ancient-Germanic term for “father.” Cognate terms appear across Germanic languages, including Old English fæder, Old High German fater, German Vater, and Dutch vader. The Old Norse form faðr reflects typical phonological developments in the Norse branch, including the retention of the eth consonant ð and related vowel patterns.

Attestation and usage: In Old Norse texts, forms related to faðr appear in genealogical passages, poetry, and prose that discuss family and lineage. The exact inflected forms and spelling can vary by manuscript tradition, and faðr as a standalone lexical form is understood within the broader family of terms for “father.” The more common modern Icelandic form is faðir, used in everyday language and modern writing.

Significance: Faðr illustrates the shared Germanic heritage of family terms and the historical development of Scandinavian languages, including orthographic changes involving ð and corresponding phonological shifts. It provides insight into how the word evolved from itsProto-Germanic roots into the modern lexicon of Icelandic and related languages.
