Five Families of Nouns
Each declension has its own set of case endings.
How It Works
| Declension | Genitive ending | Dictionary form | Meaning |
|---|---|---|---|
| first | -ae | puella, puellae | girl |
| second | -i | amicus, amici | friend |
| second (neuter) | -i | verbum, verbi | word |
| third | -is | rex, regis | king |
| fourth | -us | manus, manus | hand |
| fifth | -ei | res, rei | thing |
The first two declensions hold most of the words you meet at the start. The third is the biggest group. The fourth and fifth are small, but they hold common words such as manus (hand), domus (house) and res (thing). This course teaches them in order.
One declension can hold more than one gender. The second declension holds masculine nouns such as amicus and neuter nouns such as verbum. Learn the gender with each noun.
