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:
 * durities, eluvies, ingluvies, mollities

not found: amaritierum

To add: pernicies
