Reconstruction:Proto-Germanic/nasō

Etymology
From. Compare 🇨🇬.

May, in Proto-Germanic, have been a plurale tantum, whose nominative ending *-ō goes back to the Proto-Indo-European thematic nominative dual ending, while the other cases displayed consonant-stem plural endings -ǭ, -miz, -unz. This presupposes a Proto-Germanic consonant stem.

Griepentrog prefers to reconstruct, following Rasmussen, the original Proto-Indo-European paradigm as an acrostratic paradigm with rare ablaut a ~ ā: nom. sg. *Hnā́s-s, acc. sg. *Hnā́s-m̥, gen. sg. *Hnás-s (> *Hnás-os), dat. sg. *Hnás-ey, nom. du. *Hnā́s-h₁, nom. pl. *Hnā́s-es, acc. pl. *Hnás-m̥s.

Griepentrog also considers the zero-grade form *nus- instead of **uns- regular, adducing parallels. Forms in *nus- may be additionally analogically influenced by a Proto-Indo-European verb.
