1. Nominative: Subject of the verb
2. Genitive: Possession, relationship, or belonging
3. Dative: Indirect object
4. Accusative: Direct object
5. Ablative: Prepositional phrases, means, manner, time, place
6. Vocative: Direct address
Each case has two numbers: singular and plural. Therefore, a Latin noun can have a total of 12 forms (6 cases x 2 numbers).
Example:
The noun "puer" (boy) has the following forms:
| Case | Singular | Plural |
|---|---|---|
| Nominative | puer | pueri |
| Genitive | pueri | puerorum |
| Dative | puero | pueris |
| Accusative | puerum | pueros |
| Ablative | puero | pueris |
| Vocative | puer | pueri |
Note: Some nouns have irregular declensions, meaning their forms don't follow the standard patterns. However, the basic principle of 6 cases and 2 numbers remains the same.
