B. Neuter ĭ-Stems.

[39]. These end in the Nominative Singular in -e, -al, and -ar. They always have in the Ablative Singular, -ia in the Nominative, Accusative, and Vocative Plural, and -ium in the Genitive Plural, thus holding more steadfastly to the i-character than do Masculine and Feminine ĭ-Stems.

Sedile, seat;
stem, sedīli-.
Animal, animal;
stem, animāli-.
Calcar, spur;

1. In most words of this class the final -i of the stem is lost in the Nominative Singular; in others it appears as -e.

2. Proper names in -e form the Ablative Singular in -e; as, Sōracte, Mt. Soracte; so also sometimes mare, sea.

III. Consonant-Stems that have partially adapted themselves to the Inflection of ĭ-Stems.

[40]. Many Consonant-Stems have so far adapted themselves to the inflection of ĭ-stems as to take -ium in the Genitive Plural, and -īs in the Accusative Plural. Their true character as Consonant-Stems, however, is shown by the fact that they never take -im in the Accusative Singular, or in the Ablative Singular. The following words are examples of this class:—

Caedēs, f., slaughter;
stem, caed-.
Arx, f., citadel;
stem, arc-.
Linter, f., skiff;
stem, lintr-.

1. The following classes of nouns belong here:—

a) Nouns in -ēs, with Genitive in -is; as, nūbēs, aedēs, clādēs, etc.

b) Many monosyllables in -s or -x preceded by one or more consonants; as, urbs, mōns, stirps, lanx.

c) Most nouns in -ns and -rs as, cliēns, cohors.

d) Ūter, venter; fūr, līs, mās, mūs, nix; and the Plurals faucēs, penātēs, Optimātēs, Samnitēs, Quirītēs.

e) Sometimes nouns in -tās with Genitive -tātis; as, cīvitās, aetās. Cīvitās usually has cīvitātium.
