Ni kritikas la filmon kaj legas la subtitolojn.

Ni means we.

Like English we, it can refer to the speaker plus one or more other people. The sentence does not tell you exactly who is included; context does that.

The ending -as marks the present tense in Esperanto.

So:

• kritikas = criticize / criticizes / am criticizing / are criticizing / is criticizing
• legas = read / reads / am reading / are reading / is reading

Esperanto uses the same present-tense ending -as for all persons.

No. Esperanto verbs do not change for person or number.

So you get:

• mi legas = I read / am reading
• vi legas = you read / are reading
• li legas = he reads / is reading
• ni legas = we read / are reading

The verb form stays legas every time.

The ending -n marks the direct object in Esperanto. This is often called the accusative ending.

In this sentence, the things receiving the action are:

• la filmon = the film
• la subtitolojn = the subtitles

So:

• we criticize the film
• we read the subtitles

That is why those nouns take -n.

Because it is both plural and a direct object.

The parts are:

• subtitolo = subtitle
• subtitoloj = subtitles
• subtitolojn = subtitles, as a direct object

So the order is:

• -o = noun
• -j = plural
• -n = accusative / direct object

This same pattern appears with many Esperanto nouns.

La is the definite article, meaning the.

Esperanto has only one article:

• la = the

It does not normally use a separate indefinite article like English a or an. So:

• filmo can mean a film or just film, depending on context
• la filmo means the film

In your sentence, la filmon and la subtitolojn are definite: the film and the subtitles.

Because both noun phrases are definite:

• la filmon
• la subtitolojn

In Esperanto, it is normal to repeat la when it belongs to each noun separately. English often does the same: the film and the subtitles.

So la filmon kaj la subtitolojn is the natural way to say the film and the subtitles.

Because the same subject, ni, applies to both verbs.

So the sentence works like:

• Ni kritikas la filmon kaj legas la subtitolojn.
• literally: We criticize the film and read the subtitles.

Esperanto, like English, often omits the repeated subject when one subject does two actions.

You could say Ni kritikas la filmon kaj ni legas la subtitolojn, but that is less natural unless you want extra emphasis.

It can mean either, depending on context.

Esperanto -as covers what English often splits into:

• simple present: we read
• present progressive: we are reading

So Ni kritikas la filmon kaj legas la subtitolojn could mean:

• We criticize the film and read the subtitles
• or We are criticizing the film and reading the subtitles

Usually the situation makes the intended meaning clear.

The normal, neutral order is:

• Ni = subject
• kritikas / legas = verbs
• la filmon / la subtitolojn = objects

So the sentence follows a straightforward subject–verb–object pattern.

But Esperanto word order is fairly flexible because the -n ending shows which nouns are objects. That means other orders are possible for emphasis, though the given version is the most neutral and beginner-friendly.

Esperanto nouns normally end in -o.

Here you have:

• filmo = film
• subtitolo = subtitle

Then extra endings are added:

• filmo
  • -n → filmon
• subtitolo
  • -j
    • -n → subtitolojn

This is a very common Esperanto pattern: a clear root plus regular endings.

Kaj means and.

It connects the two actions:

• kritikas la filmon
• legas la subtitolojn

So the whole sentence says that we are doing both actions.
