Reconstruction

Ringe and Taylor reconstruct *sunu for Proto-West Germanic,[1] and Wiktionary has the same form.[2]

Etymology

It is inherited from Proto-Germanic *sunuz (“son”),[1][3] which Kroonen cites by its stem *sunu- and Orel as *sunuz.[3][4] With the loss of final *-z the nominative *sunuz and the accusative *sunų merged in *sunu.[5] Stiles counts this loss of final *-z in words of more than one syllable, with Old English and Old High German sunu against Gothic 𐍃𐌿𐌽𐌿𐍃 (sunus) as his example, among the shared innovations of the West Germanic languages.[6] The genitive singular *sunauz became Proto-West Germanic *sunō, as all remaining diphthongs in unstressed syllables became long mid vowels.[7]

Morphology

A masculine u-stem.[8][9] Ringe and Taylor's Proto-West Germanic paradigm has the singular *sunu, *sunu, genitive *sunō, dative *suniwi or *-ō, instrumental *sunu, and the plural *suniwi or *-ō, *sunų̄, genitive *suniwō (perhaps *-awō), dative *sunum; the forms in *-ō and *-aw- belonged to the northern dialects.[10] Hogg and Fulk trace the Old English paradigm to an early Proto-Germanic one with the same endings on heavy and light stems.[11]

Evidence

The noun is attested in all the West Germanic languages: Old English sunu, Old Frisian sunu, Old Saxon sunu and Old High German sunu.[12] In Old Dutch, ONW records suno in the Utrecht baptismal vow of 791–800, the Old Low and Middle Franconian psalms of the 10th century and later texts.[13] Old Saxon has the genitive suno possibly at Heliand line 5788.[7][14] In Old High German the oldest texts keep the u-stem sunu, but after the loss of the final -u the word passed entirely into the i-stems as sun.[9]

Competing analyses

Ringe and Taylor see in this word a division of the West Germanic dialects before the loss of *-i in third syllables.[15] Old High German keeps the dative singular ending as ⟨-iu⟩, but Old English and Old Frisian have suna in the genitive singular, the dative singular and the nominative plural alike.[15] Rather than a spread of the genitive ending, they prefer to suppose that the sequence *-iw- in the u-stem endings was replaced by *-aw- very early in the northern West Germanic dialects, as partly in Gothic.[15]

Meanings

  1. son[1][2]

Old English also used the noun for "descendant" and "young of an animal".[16]

Derivatives

  • *swestersunu "sister's son", which Wiktionary reconstructs;[17] Old English has sweostorsunu, and Köbler compares Old Frisian and Old High German compounds.[18]
