User:Urszag/Fifth-declension

Certain grammars indicate that fifth-declension nouns in Latin are generally defective in the plural, lacking attested genitive forms in -erum or ablative/dative forms in -ebus. I'm going to try to find out which nouns are attested with these forms.

Another topic that I've been wondering about is whether -ies abstract nouns with a synonymous form in -ia should be categorized as alternative forms or as synonyms.


I found an attested plural form in -erum and/or -ebus for:

To add: pernicies

I failed to find any such form for:

Attested, but not sure what citation to use:

  • acies

No entries yet: adluvies, alluvies, amicities, balbuties, conluvies, fallacies, pigrities

  • L&S: lenities, imperfundies, intergeries, interluvies, magnities/magnicies, prosicies, pullities, saevities, sordities, tardities, vanities
  • factispecies

Words (or pairs of words) with both -ies and -ia forms:

Newly entered, rare: barbaries, immundities, segnities, spurcities, tristities
