Lesson 2: Nouns

Similiar to verbs, Latin nouns change their ending based on certain characteristics. Here, the characteristics are known as the case of the noun. The following table summarizes the six different cases that a noun can take. Latin does not have articles ("a", "an", or "the") so they must be provided in translation.

Case English Part of Speech Examples
Nominative Subject He, she, it, they, you, I
Genitive Possessive His, her, its, their, your, my
Dative Indirect object to him, to her, to it, to them, to you, to me
Accussative Direct Object saw him, saw her, saw it, saw them, saw you, saw me
Ablative Object of the Preposition by/with/from him, her, it, them, you, me
Vocative Exclamation "Oh father (vocative case)! Help me!"
These six cases must be distiguished in order to decline (conjugate for nouns/adjectives) correctly. It is important to note that the vocative case takes the same form as the nominative, with one exception which is not discussed here.

Now that we understand cases, we can look at the types of adjectives. There are two parts to categorizing nouns: number of declension and gender. Vocab entries consist of the nominative and genitive forms of verbs with the gender in parenthesis. Now that we know the basics of nouns, we can look at the two declesions.

Declension

Each declension, 1st and 2nd, follow the same pattern of endings. For the most part, 1st declension nouns are feminine, but some masculine as well. Mostly masculine and neuter make up the 2nd declension. As previously mentioned, a noun's declension determines the ending, but in order to make an adjective-noun pair, the gender of the noun must be known. The steps to decline a noun are slightly different from verb conjugation.

  1. Find the root of the noun.
  2. Determine the correct ending based on the declension.
  3. Add the ending to the root.
Same basic principles with a twist. The root of nouns is the genitive form without the ending. So for the noun porta, portae (f.), the root is port. Nominative forms do not always follow the root so both nominative and genitive must be known to fully decline a noun.

The following is a table showing the endings of the three types of declesions for the nouns: porta, portae (f.); Amīcus, Amīcī (m.); and Dōnum, Dōnī (n.).

1st Declesion Singular Plural
Nominative Port-a Port-ae
Genitive Port-ae Port-ārum
Dative Port-ae Port-īs
Accussative Port-am Port-ās
Ablative Port-ā Port-īs
Vocative Port-a Port-ae
2nd Declension Singular Plural
Nominative Amīc-us Amīc-ī
Genitive Amīc-ī Amīc-ōrum
Dative Amīc-ō Amīc-īs
Accussative Amīc-um Amīc-ōs
Ablative Amīc-ō Amīc-īs
Vocative Amīc-e Amīc-ae
2rd Declension Singular Plural
Nominative Dōn-um Dōn-a
Genitive Dōn-ī Dōn-ōrum
Dative Dōn-ō Dōn-īs
Accussative Dōn-um Dōn-a
Ablative Dōn-ō Dōn-īs
Vocative Dōn-um Dōn-a
