Lesson 4: The Second Declension, Masculine; The Genitive Case

New Concepts

vocative
The vocative case was mentioned in the first lesson, but we didn't focus on it yet because it was the same as the nominative in the first declension. The second declension is the only time the vocative is different, and only in most words ending in -us or -ius. The vocative case is used to address someone or something: Boys, come here! Death, where is thy sting?

Forms

The Second Declension

Nouns of the second declension all end in -i in the genitive case. Unlike first declension nouns, which all have the same -a ending in the nominative, their nominative endings can differ, so we use the genitive ending to recognize them as second declension nouns. Most masculine second declension nouns end in -us, -ius, or -er in the nominative case.

Nouns of the second declension may be masculine or neuter, just as nearly all first declension nouns were feminine. We will only focus on the masculine nouns in this lesson. The second declension masculine endings are:

Case Singular Plural
Nominative (varies) -i
Genitive -i -orum
Dative -o -is
Accusative -um -os
Ablative -o -is

If you compare these endings to the first declension endings, you'll see some similarities that may help you remember them. The dative and ablative are the same, as they were in the first declension plural, and the genitive plural has a 'rum' sound.

We decline a noun by adding these endings to the stem, which is found by removing the -i from the genitive. Let's start with a -us word, amicus, amici, meaning “friend”.

Case Singular Plural
Nom. amicus amici
Gen. amici amicorum
Dat. amico amicis
Acc. amicum amicos
Abl. amico amicis

Now we'll do one that ends in -er: puer, pueri, meaning “boy”.

Case Singular Plural
Nom. puer pueri
Gen. pueri puerorum
Dat. puero pueris
Acc. puerum pueros
Abl. puero pueris

Here's another -er word, ager, agri, meaning “field”. Note that unlike puer, ager drops the 'e' in the genitive. Remember that we get the stem for forming all the cases from the genitive, not the nominative; so we always learn the genitive along with the nominative when we learn a new word.

Case Singular Plural
Nom. ager agri
Gen. agri agrorum
Dat. agro agris
Acc. agrum agros
Abl. agro agris

And here's one ending in -ius: filius, fili, meaning “son”. Nouns like filius are slightly different, in that they drop the extra -i in the genitive singular. So the stem is actually fili-, but the genitive is fili, not filii. All other forms are as expected, adding the endings to the stem fili:

Case Singular Plural
Nom. filius filii
Gen. fili filiorum
Dat. filio filiis
Acc. filium filios
Abl. filio filiis

The Vocative Case

As mentioned above, the vocative only differs from the nominative in the second declension singular, and only in nouns ending in -us and -ius. Filius and proper names ending in -ius (like Lucius) form the vocative with -i:

Nouns ending in -us form the vocative with -e:

One exception to this last rule is deus, meaning “god”. The vocative of deus is deus. So in prayers starting with “O God,” you'll see Deus, not Dei or something like that.

Syntax

The Genitive Case

As we touched on very lightly before, possession is shown by the genitive case:

The owner may come before or after the thing owned, but you'll normally see the two words together in the sentence. When translating to Latin, try not to put a genitive between two nouns, since that would make it hard to tell which thing is being owned.
