[woge]
** German
[lang=de]
*** Alternative forms
- [de] [obsolete]
*** Etymology
With dialectal _-ā-_ → _-ō-_ from northern [de], borrowed from [de]. The
latter form could be a mere alteration of the rare masculine [gml], from [de],
from [de], from [de] (which see for cognates); ultimately from [de].
However, the feminine may also go back to an unattested [osx] (with a short
vowel), from [gem-pro] (or similar), related with [gem-pro] (which is from
[de]). The evidence for this is [gmh], from [goh]. In Middle Low German and
Middle Dutch, this feminine noun would have widely merged with the
aforementioned [gml], [osx] per open-syllable lengthening.
