Appendix:Latin second declension
Contents |
Description [edit]
Latin words of the second declension are generally of masculine gender (ending in -us) or neuter gender (ending in -um), and have a genitive in -ī.
Latin words borrowed from Ancient Greek’s second declension are inflected with a varying mixture of Greek and Latin endings.
Examples [edit]
Masculine [edit]
Citation form: mūrus, -ī m
| Case | Singular | Plural |
|---|---|---|
| nominative | mūr·us | mūr·ī |
| genitive | mūr·ī | mūr·ōrum |
| dative | mūr·ō | mūr·īs |
| accusative | mūr·um | mūr·ōs |
| ablative | mūr·ō | mūr·īs |
| vocative | mūr·e | mūr·ī |
| locative | mūr·ī | mūr·īs |
Citation form: filius, -ī m
| Case | Singular | Plural |
|---|---|---|
| nominative | fili·us | fili·ī |
| genitive | fili·ī | fili·ōrum |

| accusative | fili·um | fili·ōs |
| ablative | fili·ō | fili·īs |
| vocative | fil·ī | fili·ī |
| locative | fili·ī | fili·īs |
N.B. The singular vocative of second declension -us nouns is the only place in which the vocative ever differs from the nominative forms: -e instead of -us. The plural vocative is the same as the nominative. As seen in filius, filiī, the vocative singular changes the -ius into an -ī, instead of changing the -us into an -e.
