Third Declension i-base

[AureliaeLacrimae]

Well, this one is very similar to the consonant base, but there are some minor differences, which are mostly realised through cases.

There are subtypes here as well:

parisyllaba with endings -is, -is and -es, is such as navis, navis, f ship and nubes, nubis, f coloud

imparisyllaba with the endings -s, -is (usually feminine)  such as pars, partis - a part, and  -er, -ris (usually masculine) imber, imbris - rain

And, of course, subtypes for the nouns of the neuter:

-e, -is      mare, maris, n        sea

-al, -alis    animal, animalis, n  animal

-ar, -aris  calcar, calcaris, n    spur (for horses)

Here are some examples with differences coloured in red:

        Singular

N        navis            pars            mare

G        navis          partis            maris

D        navi            parti              mari

Acc    navem          partem        mare

V        navis            pars            mare

Ab      nave            parte            mari

      Plural

N      naves            partes        maria

G      navium          partium        marium

D      navibus          partibus      maribus

Acc    naves            partes        maria

V      naves            partes        maria

Ab      navibus          partibus      maribus

Some of the nouns (such as navis and pars) have lost the -i in some cases and it had become -e instead. Nevertheless, we still consider them as i-base nouns because their genitive has remained -ium and hadn't contracted to -um.

Neuter nouns:

Remember the neuter rule? N=Acc=V? Plural of these cases ends with -a? Well, here you also follow these rules. However, you also have an additional -i before -a, so it's -ia (e.g. maria not mara).

Also, neuter nouns of this declension had kept the -i in ablative! (compare nave and mari)

Thanks a lot for that detailed explanation!
