[444]. Greek appellatives always take a Latin form in the dative singular and in the plural, and usually throughout: thus, poēta, M., poet, and aula, F., court, are declined like mēnsa. Masculines have sometimes a nominative -ēs and accusative -ēn: as, anagnōstēs, reader, anagnōstēn; rarely an ablative -ē: as, sophistē, sophist. Greek feminines in -ē sometimes have Greek forms in late writers: as, N. grammaticē, philology, G. grammaticēs, Ac. grammaticēn, Ab. grammaticē (Quintil.).

[445]. Greek proper names sometimes have the following forms. Nominative masculine -ās, -ēs: as, Prūsiās, Atrīdēs; feminine -ā: as, Gelā, Phaedrā; -ē: as, Circē. Genitive feminine -ēs: as, Circēs. Accusative masculine -ān, -dēn: as, Aenēān, Pēlīdēn; feminine -ēn: as, Circēn. Ablative feminine -ē: as, Tīsiphonē. Vocative -ā or -a: as, Atrīdā, Atrīda, Thyesta; -tē: as, Boōtē; -dē: as, Aeacidē.

[STEMS IN -o-.]

The Second Declension.

Genitive singular -ī, genitive plural -ō-rum.

[446]. Stems in -o- include substantives and adjectives, masculine or neuter.

[447]. Most names of plants in -us are feminine ([407]); also the following: alvos or alvus, belly, colus, distaff, domus, house, humus, ground, vannus, fan.

[448]. The nominative of masculines ends, including the stem vowel, in -o-s, or usually -u-s; some end in -r; neuters end in -o-m, or usually -u-m.

[449]. (1.) Stems in -o- with the nominative in -us or -um are declined as follows:
