Nominative and Accusative Plurals

Making nouns plural in both cases

From One to Many

So far, we've been dealing with single things - one girl, one master. But what happens when we want to talk about multiple things? Just like English changes "girl" to "girls", Latin changes its endings to show plural (more than one).

Here's the brilliant part: Latin plural endings follow clear patterns! Once you learn these patterns, you can make any noun plural. The nominative and accusative cases still do the same jobs - they just represent multiple people or things now.

Remember: The case tells us the job (subject or object), and singular/plural tells us how many. So we have four forms total for each declension!

The Plural Patterns

Here are the plural endings for both declensions. Notice how different they are from the singular - this makes it easy to spot whether we're talking about one or many!

Declension Case Singular Plural Pattern to Notice
1st (fem.) Nominative -a
-ae
Like 'antennae'
Accusative -am
-as
Just add 's' to the 'a'
2nd (masc.) Nominative -us
-i
Like 'cacti' or 'fungi'
Accusative -um
-os
Changes to 'os'

Complete Forms: Singular and Plural

Let's see how our familiar words change from singular to plural. Click each example to reveal:

puella → puellae
girl → girls (nom.)
puellam → puellas
girl → girls (acc.)
dominus → domini
master → masters (nom.)
dominum → dominos
master → masters (acc.)
Quick tip: Notice how the verb also changes? When the subject is plural, the verb becomes plural too! amat → amant, laborat → laborant

Practice Sentences

Now let's see plurals in action. Click each sentence to reveal the translation. Pay attention to how the endings tell you who's doing what and how many there are!

Mixed Singular and Plural
puellae servum vocant.
dominus ancillas laudat.
servi dominos timent.
ancilla puellas amat.
amici villas intrant.
Pattern spotting: Can you see how -ae/-i means "they" are doing something, while -as/-os means something is happening to "them"?
