La teritorio estas granda.

La is the Esperanto definite article, equivalent to the in English.

So la teritorio means the territory, not just a territory or territory in general.

A useful point for English speakers: la never changes. It does not have different forms for:

• singular vs. plural
• masculine vs. feminine
• different cases

It is always just la.

In Esperanto, nouns normally end in -o.

So:

• teritori- = the root
• -o = noun ending

That tells you immediately that teritorio is a noun.

This is one of the most helpful features of Esperanto: word endings clearly show the part of speech.

Yes. Teritorio is a very transparent cognate for an English speaker.

Many Esperanto words are built from roots that look familiar if you know English, especially words of Latin or Romance origin. Here:

• English: territory
• Esperanto: teritorio

The Esperanto form follows regular spelling and noun formation rules.

Estas is the present-tense form of esti, which means to be.

So estas can mean:

• am
• is
• are

depending on context.

In this sentence, estas means is.

One important difference from English: Esperanto verbs do not change according to the subject. So:

• mi estas = I am
• vi estas = you are
• li estas = he is
• la teritorio estas = the territory is

The verb form stays estas every time.

In Esperanto, adjectives end in -a.

So:

• grand- = the idea of largeness or greatness
• -a = adjective ending

That makes granda mean large, big, or great depending on context. In this sentence, it means large/big.

It is granda because it is an adjective describing the noun.

Here is the difference:

• granda = adjective, large
• grande = adverb, largely or in a great way
• grandon = accusative form of a noun or adjective in certain contexts, which is not needed here

In La teritorio estas granda, granda is a predicate adjective after estas, so the normal adjective form -a is used.

Because this sentence does not need the accusative.

In Esperanto, -n is often used for the direct object. But here:

• la teritorio is the subject
• estas is a linking verb
• granda describes the subject

With esti (to be), the adjective after the verb is not a direct object. It is just describing the subject, so no -n is used.

That is why:

• La teritorio estas granda. = correct

not:

• La teritorio estas grandan. = incorrect in normal usage

This sentence is singular because it is talking about one territory:

• la teritorio = the territory
• estas = is
• granda = large

If you want the plural, Esperanto adds -j:

• la teritorioj = the territories
• grandaj = large

So:

• La teritorioj estas grandaj. = The territories are large.

Notice that the adjective agrees with the noun in number:

• singular: granda
• plural: grandaj

Yes. In Esperanto, adjectives agree with the nouns they describe in:

• number: singular or plural
• case: especially whether there is an accusative -n

So:

• la teritorio → granda
• la teritorioj → grandaj
• mi vidas la grandan teritorion → both adjective and noun take -n

In your sentence, both are singular and there is no accusative, so:

• la teritorio
• granda

Because granda is not part of the noun phrase la teritorio here. It comes after estas and works like large in English The territory is large.

Compare:

• La teritorio estas granda. = The territory is large.
• La granda teritorio = the large territory

In the first sentence, granda is a predicate adjective after the verb. In the second, granda directly modifies the noun inside the noun phrase.

Yes, adjectives can often come either before or after the noun in Esperanto when they are directly modifying it.

For example:

• la granda teritorio
• la teritorio granda

Both are possible, though the first is usually more natural for many learners.

But in your sentence, granda is not just sitting next to the noun as an attributive adjective. It is linked by estas, so the structure is different:

• La teritorio estas granda.

Yes, Esperanto word order is fairly flexible, but the basic order here is the most neutral and natural:

• La teritorio estas granda.

You may also see other orders for emphasis or style, such as:

• Granda estas la teritorio.

That can sound more literary or emphatic, something like Large is the territory.

For beginners, the standard pattern subject + verb + complement is the best one to use.

A simple pronunciation guide is:

lah teh-ree-toh-REE-oh ESS-tahs GRAHN-dah

A few helpful points:

• a is like a in father
• e is like e in met
• i is like ee in see
• o is like o in for but shorter and cleaner
• stress usually falls on the second-to-last syllable

So:

• teritorio → te-ri-to-RI-o
• estas → ES-tas
• granda → GRAN-da

Not always. Granda can mean:

• big
• large
• sometimes great, depending on context

In this sentence, large is often the most natural translation:

• The territory is large.

But the exact English word depends on context and style.

Because Esperanto verbs are much more regular than English verbs.

In the present tense, every subject uses -as:

• mi estas = I am
• vi estas = you are
• ŝi estas = she is
• ili estas = they are

This is one of the ways Esperanto reduces memorization. You do not need to learn separate present-tense forms for each person.

If you say:

• Teritorio estas granda

that usually sounds less natural in Esperanto as a normal sentence, because a singular countable noun often needs either:

• an article like la, or
• some other determiner, or
• a context that makes the meaning clear

Most likely, you would normally say:

• La teritorio estas granda. = The territory is large.
• Tiu teritorio estas granda. = That territory is large.
• Teritorioj estas grandaj. = Territories are large. / Territories are large things.

So in this sentence, la helps make it a normal, specific statement.

The dictionary forms are:

• la = the
• teritorio = territory
• esti = to be
• granda = large, big

Notice that estas is not the dictionary form of the verb. The dictionary form is esti. The -as ending shows present tense.
