La kampo estas granda.

In Esperanto, -o is the regular ending for a noun.

So:

• kampo = a noun meaning field
• many Esperanto nouns work the same way:
  • domo = house
  • libro = book
  • hundo = dog

This makes it easy to recognize the part of speech right away.

La is the definite article, so it means the.

In La kampo estas granda, it shows that we are talking about the field, not just any field.

A few useful points:

• Esperanto has only one definite article: la
• it does not change for gender, number, or case in normal use
• Esperanto has no indefinite article like English a or an

So:

• la kampo = the field
• kampo = a field or just field, depending on context

Because -a is the regular ending for an adjective in Esperanto.

So:

• granda = big / large
• other examples:
  • bona = good
  • nova = new
  • verda = green

This is one of Esperanto’s basic patterns:

• nouns end in -o
• adjectives end in -a
• adverbs end in -e

So granda is an adjective describing kampo.

Because granda is describing a noun, not modifying a verb.

Compare:

• La kampo estas granda. = The field is large.
  Here granda is an adjective describing kampo.

• La kampo kreskas grande. would try to use an adverb, which is not what you want for this kind of description.

In Esperanto:

• -a = adjective, used for nouns
• -e = adverb, used for verbs, adjectives, or whole clauses

So after estas, you normally use an adjective if you are describing the subject.

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

So:

• estas = is / am / are

A very important feature of Esperanto is that the verb does not change depending on the subject.

For example:

• mi estas = I am
• vi estas = you are
• li estas = he is
• ili estas = they are

So in this sentence, estas simply means is.

Because Esperanto verbs are much more regular than English verbs.

In the present tense, every subject uses -as:

• mi estas
• vi estas
• la kampo estas
• ili estas

You do not need to memorize different present-tense forms for different persons. That is one of the easiest parts of Esperanto grammar for English speakers.

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

Here both words are singular and not in the accusative, so we get:

• kampo
• granda

If the noun changed, the adjective would change too:

• La kampoj estas grandaj. = The fields are large.
• Mi vidas la grandan kampon. = I see the large field.
• Mi vidas la grandajn kampojn. = I see the large fields.

So agreement affects:

• number: singular or plural
• case: especially the accusative -n

Because kampo is the subject of the sentence, not the direct object.

The -n ending is usually used for the direct object.

In this sentence:

• La kampo = the subject
• estas granda = what is being said about the subject

Since kampo is not receiving the action of a verb, it stays kampo, not kampon.

Yes, but that would create a different sentence structure.

• La kampo estas granda. = The field is large.
  Here granda is a predicate adjective after estas.

• La granda kampo = the large field
  Here granda directly modifies the noun inside the noun phrase.

So both are correct, but they are used differently:

• la kampo estas granda = a full sentence
• la granda kampo = a noun phrase, not a complete sentence by itself

The normal order is:

• La kampo — subject
• estas — verb
• granda — predicate adjective

So La kampo estas granda is the most natural basic order.

Esperanto word order is somewhat flexible, but this standard order is the best one for learners to use first. Because the sentence is simple and neutral, this is exactly how you would usually say it.

A simple rough guide is:

lah KAHM-poh ESS-tahs GRAHN-dah

A few pronunciation notes:

• a is like a in father
• e is like e in bet, but often a bit clearer and steadier
• o is like a pure o, not the English diphthong in go
• stress usually falls on the second-to-last syllable:
  • KAM-po
  • ES-tas
  • GRAN-da

Esperanto pronunciation is much more regular than English spelling, so once you learn the sounds, words are usually pronounced exactly as written.

Yes. In many basic contexts, granda can be translated as either big or large.

So:

• La kampo estas granda. can naturally mean:
• The field is big.
• The field is large.

Which English word sounds better depends on context and style, but the Esperanto word itself is completely normal for both.

Grammatically, kampo is a valid word, but without la, the sentence usually sounds less natural for this kind of everyday statement.

La kampo estas granda is the normal way to say The field is large when you mean a specific field.

If you remove la, the meaning becomes less clearly definite, and the sentence may sound odd unless the context strongly supports it.

So for learners, the safest choice here is:

• La kampo estas granda.
