Latin is a fascinating language that can help us understand the roots of many modern Western languages, including English, French, and Spanish. In order to develop a strong grasp of Latin, it is crucial to have a solid understanding of its grammar rules, especially those related to declensions. In this lesson, we will dive deep into the concept of noun declensions, including the five different declensions and their respective endings.

What are Noun Declensions
In Latin, nouns are inflected to reflect the case, number, and gender of the subject they refer to. A declension is a set of endings added to a noun or an adjective to indicate its grammatical function in a sentence. In other words, declensions are a series of forms (or endings) that change based on the noun's function in the sentence.
In Latin, there are five different noun declensions, each with its own set of endings. These declensions are labeled by number (first through fifth) and are determined by the endings of the nominative singular and genitive singular forms of the noun.
First Declension
The first declension is typically feminine and contains many nouns that end in -a. However, not all first-declension nouns end in -a, so it is important to memorize which nouns use this declension. Here are the endings for the first declension:
| Latin | Pronunciation | English |
|---|---|---|
| puella | poo-EL-la | girl |
| fēmina | FAY-mi-na | woman |
| nauta | NOW-ta | sailor |
One example of the first-declension noun is "puella," or girl. To decline this noun, we would follow these steps:
Singular
- Nominative: puella
- Genitive: puellae
- Dative: puellae
- Accusative: puellam
- Ablative: puellā
Plural
- Nominative: puellae
- Genitive: puellārum
- Dative: puellīs
- Accusative: puellās
- Ablative: puellīs
Note that the endings in the plural form are different from those in the singular form. It is important to memorize these endings for each of the five declensions.
Second Declension
The second declension includes masculine and neuter nouns that end in -us, -er, or -um. Here are the endings for the second declension:
| Latin | Pronunciation | English |
|---|---|---|
| servus | SER-wus | slave |
| puer | PU-er | boy |
| templum | TEM-plum | temple |
One example of a second-declension noun is "puer," or boy. Here are the steps to decline this noun:
Singular
- Nominative: puer
- Genitive: puerī
- Dative: puerō
- Accusative: puerum
- Ablative: puerō
Plural
- Nominative: puerī
- Genitive: puerōrum
- Dative: puerīs
- Accusative: puerōs
- Ablative: puerīs
Note that the genitive singular form is the only one that drops the -er ending in the second declension. All other forms follow the same pattern as with the first declension.
Third Declension
The third declension is composed of both masculine, feminine, and neuter nouns, and does not follow any specific pattern. Here are the endings for this declension:
| Latin | Pronunciation | English |
|---|---|---|
| rex | reks | king |
| amīcus | ah-MEE-kus | friend |
| corpus | KOR-pus | body |
One example of a third-declension noun is "rex," or king. Here are the steps to decline this noun:
Singular
- Nominative: rex
- Genitive: rēgis
- Dative: rēgī
- Accusative: rēgem
- Ablative: rēge
Plural
- Nominative: rēgēs
- Genitive: rēgum
- Dative: rēgibus
- Accusative: rēgēs
- Ablative: rēgibus
Note that the third declension has many irregular patterns, and it is important to memorize the endings for each individual noun.
Fourth Declension
The fourth declension includes only a few nouns, and they are typically masculine. The main characteristic of this declension is the -ū ending in the nominative singular. Here are the endings for the fourth declension:
| Latin | Pronunciation | English |
|---|---|---|
| manus | MA-nus | hand |
| fructus | FRUK-tus | fruit |
| gradus | GRA-dus | step |
One example of a fourth-declension noun is "manus," or hand. Here are the steps to decline this noun:
Singular
- Nominative: manus
- Genitive: manūs
- Dative: manuī
- Accusative: manum
- Ablative: manū
Plural
- Nominative: manūs
- Genitive: manuum
- Dative: manibus
- Accusative: manūs
- Ablative: manibus
Fifth Declension
The fifth declension is typically feminine and includes only a few words. The main characteristic of this declension is the -ēs in the nominative singular. Here are the endings for the fifth declension:
| Latin | Pronunciation | English |
|---|---|---|
| rēs | res | thing |
| spēs | spes | hope |
| dīes | dee-ES | day |
One example of a fifth-declension noun is "rēs," or thing. Here are the steps to decline this noun:
Singular
- Nominative: rēs
- Genitive: rēī
- Dative: reī
- Accusative: rem
- Ablative: rē
Plural
- Nominative: rēs
- Genitive: rērum
- Dative: rēbus
- Accusative: rēs
- Ablative: rēbus
Conclusion
Understanding noun declensions is crucial for developing a strong grasp of Latin grammar, as it allows us to understand how the form of a word changes based on its function in a sentence. While memorizing the different declensions and their respective endings may seem daunting at first, constant usage and practice will eventually make it second nature.
