Reconstruction

The word is *fadēr in Ringe and Wiktionary,[1][2] *fađēr in Orel,[3] and the stem *fader- in Kroonen and Köbler.[4][5]

Etymology

It is inherited from Proto-Indo-European *ph₂tḗr (“father”), the PIE word for "father".[4][1]

Morphology

An r-stem.[6] Kroonen describes the PIE word as a hysterokinetic ter-stem, nominative *ph₂-tér, genitive *ph₂-tr-ós, accusative *ph₂-tér-m.[4] In Proto-Germanic the r-stems had been reduced to five kinship terms inflected alike, the masculines *fadēr and *brōþēr and the feminines *mōdēr, *swestēr and *duhtēr; the nominative singular ended in *-ēr, the accusative probably in *-arų, the vocative in *-ar.[6]

Two sound laws shaped the word: the laryngeal between consonants became a vowel *ə, which merged with *a in the first syllable, so that *ph₂tḗr gave *pətḗr;[7] and since the accent followed, Verner's law turned the *þ of *faþḗr into *d.[1] Kroonen thinks the suffix accent of *mōdēr is analogical to this word.[8]

Evidence

The word is attested in all three branches: Gothic 𐍆𐌰𐌳𐌰𐍂 (fadar), Old Norse faðir, and Old English fæder, Old Frisian feder, Old Saxon fadar and Old High German fater in West Germanic.[4] The Gothic form occurs once, as a vocative in "abba fadar" at Galatians 4:6; elsewhere Wulfila uses Gothic 𐌰𐍄𐍄𐌰 (atta).[9][3] Its cognates include Tocharian A pācar, Sanskrit पितर्- (pitár-), Ancient Greek πατήρ (patḗr), Latin pater and Old Irish athir.[4][3]

Meanings

  1. father[4][3][2]

Old High German also used the word for "abbot",[10] and Old Frisian for "confessor".[11] De Vries reports J. Trier's view that the word named a legal rather than a biological relation, the father as the head of the family.[12]

Derivatives

  • *fadurwjan- "father's brother", which Kroonen takes as a PIE formation, like Sanskrit पितृव्य (pitṛvya) and Latin patruus.[13] Orel writes it *fađurwjōn.[3]
  • *fadrīnaz "paternal" and *fadurlīkaz "fatherly".[2]
  • Compounds: *fadurgardaz "father's house" and *fadurbanô "patricide";[2] in Orel, *steupa-fađēr "stepfather" and *fōstra-fađēr "foster father".[3]

  • Old English: fæder (“father”)[15]
