The document discusses the genitive case in Latin. The genitive case is used to show possession. It does this through genitive endings added to the ends of nouns. The endings are -ae for first declension nouns, -i for second declension nouns, and -is for third declension nouns. Examples are provided that demonstrate using the genitive case to indicate relationships like "Gaia is Julia's daughter" and "Spurius is Gaius' son."

1. The Genitive Case
Show Possession

2. In English we show possession with
‘s, s’, or the preposition OF.
e.g. (for example)
This is Julia’s book.
The girls’ mom will be
here soon.
The commander of the
troops withdrew from
the field.

3. In Latin we use genitive endings to make
a word show possession. Here are those
endings:
1st 2nd 3rd
Sing. -ae -i -is
Plural -arum -orum -um

4. Here are some examples of the Genitive
case from your reading.
Gaia est filia Iuliae. -ae is genitive sing. – 1st declension
Gaia is the daughter of Julia.
Gaia is Julia’s daughter.
Spurius est filius Gai. -i is genitive sing. – 2nd declension
Spurius is Gaius’ son.
Spurius is the son of Gaius.
Comitēs meī patris adsunt. -is is genitive sing. – 3rd declension

5. Remember, it is the GENITIVE that tells you
the declension of the noun!
