Nominative and Accusative Singular

First and second declension nouns and their cases

What is a Case?

In Latin, nouns change their endings to show what job they're doing in the sentence. These different forms are called cases. Think of it like giving each noun a uniform that shows its role - just like how a referee wears stripes and a goalkeeper wears different colored gloves!

Today we'll learn about the two most important cases: the nominative (for subjects doing the action) and the accusative (for objects receiving the action).

Key Concept: The ending of a Latin noun tells us what role it plays in the sentence - just like verb endings tell us who's doing the action!

The Two Cases

Case Job in Sentence Think of it as... Example
Nominative Subject The "doer"
The girl walks
Accusative Direct Object The "receiver"
I see the girl

First and Second Declension Patterns

Latin nouns are organised into groups called declensions - like verb conjugations, but for nouns! Each declension has its own pattern of endings. The first declension is mostly feminine nouns, whilst the second declension is mostly masculine nouns.

Spot the pattern: Both declensions add -m to make the accusative! This is your key clue that something is receiving the action.

Noun Cases: First and Second Declensions

Here are the patterns for both declensions. Notice how the stem stays the same, but the endings change to show the noun's job in the sentence:

Declension Case Ending Example English
1st (fem.) Nominative
-a
puell-a
the girl (subject)
Accusative
-am
puell-am
the girl (object)
2nd (masc.) Nominative
-us
domin-us
the master (subject)
Accusative
-um
domin-um
the master (object)

Common Nouns from Both Declensions

Here are some useful nouns from both declensions. Click each card to see both cases:

puella
girl (1st decl.)
dominus
master (2nd decl.)
ancilla
slave-girl (1st decl.)
servus
slave (2nd decl.)
villa
house (1st decl.)
amicus
friend (2nd decl.)

Putting it All Together

Now let's see both declensions working together in sentences. Remember to look for the pattern: Subject (nominative) → Verb → Object (accusative).

Example Sentences
puella dominum vocat.
servus ancillam amat.
dominus villam portat.
ancilla amicum salutat.
Quick recognition: -a/-us = doing something (nominative), -am/-um = having something done to them (accusative)!
