Re: [tied] Re: Dé Danann

dia/dea: nom sg. masc. "god"
de': voc/gen sg., nom. pl
dia: acc, dat sg., gen pl
deu, deo: acc. pl.
deib: dative plural.

However, we also have Dea, genitive sg. fem. "of the goddess." We often find
this form in the early texts, Tuath(a) Dea "Tribe(s) of the Goddess" (Donann
being gloss on "Goddess").

It is certainly possible that there was some ancient confusion between the
genitive plural "of the gods" and genitive sg. fem "of the goddess"
