Subject and Object

Foundations

The plain form is the subject, and the form with -n is the object.

How It Works

Look at two sentences that use the same words.

SentenceMeaning
La kato vidas la hundon.The cat sees the dog.
La hundo vidas la katon.The dog sees the cat.

The subject is who or what does the action: la kato in the first sentence. The object is who or what receives it: la hundon. In these sentences only the object takes -n.

Grammar books call the plain form the nominative case and the form with -n the accusative case. Esperanto has only these two. Ideas such as "of" and "to" are shown by small words (de, al). In the plural, the -n goes after the -j: la hundojn. A word that stands after estas says what the subject is and takes no -n.

Examples (4)

  1. La kato vidas la hundon.

    The cat sees the dog.

    Kato is the subject, and hundon is the object with -n.

  2. La hundo vidas la katon.

    The dog sees the cat.

    The words are the same as before, but now hundo is the subject.

  3. Ana amas Kenjin.

    Ana loves Kenji.

    Ana is the subject, and the name Kenji takes -n as the object.

  4. Kofi trinkas teon.

    Kofi drinks tea.

    Teon is the object of trinkas.

Common Mistakes

  • Leaving -n off the object.

    La kato vidas la hundo.
    La kato vidas la hundon.

    Without -n the object looks like a second subject. Every object takes -n, even when the meaning is easy to guess.

The object takes -n, while the subject keeps the plain form. This builds on the idea that endings carry meaning.
