La publiko aplaŭdis la spektaklon.

Publiko means the public / the audience as a collective group, so it is normally singular in Esperanto.

Even though it refers to many people, Esperanto often treats this kind of word as one group:

• la publiko = the audience, the public
• la homoj = the people, individual persons

So in this sentence, la publiko means the audience as a whole.

The -n ending marks the direct object in Esperanto.

Here:

• la publiko = the subject, the one doing the action
• aplaŭdis = applauded
• la spektaklon = the thing being applauded

So la spektaklon gets -n because it receives the action.

Without the -n, the grammar would be incomplete or wrong in standard Esperanto.

Because publiko is the subject, not the object.

In Esperanto:

• the subject usually has no special ending
• the direct object takes -n

So:

• La publiko = the audience did the action
• la spektaklon = the show received the action

The ending -is is the Esperanto verb ending for the past tense.

So:

• aplaŭdas = applauds / is applauding
• aplaŭdis = applauded
• aplaŭdos = will applaud

This is one of the most regular parts of Esperanto: every verb in the past tense ends in -is.

Yes, often it can be.

Esperanto’s basic tense system is simpler than English. Aplaŭdis just tells you the action was in the past. Depending on context, it can correspond to:

• applauded
• was applauding
• sometimes even did applaud

If a speaker wants to stress an ongoing action, they may add extra words, but the simple past -is is often enough.

Because both nouns are definite:

• la publiko = the audience
• la spektaklon = the show

In Esperanto, if both the subject and object are definite, each one normally gets its own la.

You cannot usually use one la for both nouns.

Yes, Esperanto word order is fairly flexible because the -n ending shows the object.

The normal order is:

• La publiko aplaŭdis la spektaklon.

But these are also grammatically possible:

• La spektaklon aplaŭdis la publiko.
• Aplaŭdis la publiko la spektaklon.

Because spektaklon has -n, you can still tell it is the object.

That said, the original sentence is the most neutral and natural word order.

The basic noun is spektaklo = show, performance, spectacle.

When it becomes a direct object, Esperanto adds -n:

• spektaklo = a show / the show
• spektaklon = a show / the show as a direct object

So -n does not change the core meaning of the noun; it just shows its role in the sentence.

In Esperanto, verbs have very clear endings. Here, aplaŭdis is the verb because -is marks a past-tense verb.

A quick breakdown:

• publik-o = noun
• aplaŭd-is = verb, past tense
• spektakl-o-n = noun + object marker

These regular endings make Esperanto much easier to parse than English.

Yes. It is a very recognizable international-style word.

• publiko = public, audience
• spektaklo = spectacle, show
• aplaŭdi = to applaud

Many Esperanto words are built from roots that will look familiar to English speakers, especially in cultural or formal vocabulary.

A simple pronunciation guide is:

La publiko aplaŭdis la spektaklon
lah poo-BLEE-koh ah-plow-DEES lah spek-TAH-klon

A few helpful points:

• stress is usually on the second-to-last syllable:
  • pubLIko
  • aplaŭDIS
  • spektaKLOn
• aŭ sounds roughly like ow in cow
• every letter is pronounced clearly

Yes, but it changes the meaning.

• La publiko aplaŭdis la spektaklon = the audience applauded the show
• La publiko aplaŭdis spektaklon = the audience applauded a show / some show

So removing la makes spektaklon indefinite rather than definite.

Because publiko can cover both ideas depending on context.

In many situations, la publiko means:

• the audience in a theater or concert hall
• the public in a broader sense

In this sentence, because of spektaklon, most learners would naturally understand la publiko as the audience.

Context decides the best English translation.
