The Genitive Case v3

Understanding possession and the 'of' case

What is the Genitive Case?

The genitive case means 'of'. It is used to show possession (ownership) or that something is part of something else. Think of it as showing that one thing belongs to another.

The term "genitive" comes from Latin genesis meaning "origin" - things that are owned by somebody can be thought of as originating from them in a sense! The key thing to remember is that it's the possessor that goes into the genitive, not the thing possessed.

Key Point: In "the house of the master", the master (possessor) goes into the genitive, whilst the house (thing possessed) stays nominative or accusative depending on its job in the sentence.

Genitive Endings

Here are the genitive endings for both declensions. Notice how they're different from the nominative and accusative endings you already know:

Number Case 1st Declension (f.) 2nd Declension (m.) Meaning
Singular Nominative
puell-a
domin-us
Subject
Accusative
puell-am
domin-um
Object
Genitive
puell-ae
domin-i
Of
Plural Nominative
puell-ae
domin-i
Subject (plural)
Accusative
puell-as
domin-os
Object (plural)
Genitive
puell-arum
domin-orum
Of (plural)
Watch Out! Some endings look the same - puell-ae could be genitive singular OR nominative plural. Use context clues (especially the verb) to work out which!

How to Translate the Genitive

The genitive can be translated into English in two main ways. Both mean exactly the same thing:

villa domini
Method 1: Using 'of'
villa domini
Method 2: Using 's
Word Order: In Latin, the genitive usually comes immediately after the noun it describes: gladius domini = the master's sword, epistula puellae = the girl's letter.

Practice Examples

Let's see the genitive in action! Click each sentence to reveal the breakdown and translation. Pay attention to how you can tell whether an ending is genitive or not:

Using Context Clues
servus domini laborat.
puellae equum amant.
ancilla vinum nautarum portat.
domini cibum consumunt.
Logic Check: Always ask yourself "does this make sense?" If you translate domini as genitive in the last example, you'd get "The food of the master eats" - which is nonsense! Context is key.
