La muzeo konservas la malnovan bildon.

In Esperanto, all singular nouns end in -o. So muzeo means museum.

• muzeo = museum
• bildo = picture/image
• domo = house

This -o ending makes nouns easy to recognize.

La is the Esperanto definite article, meaning the.

So:

• la muzeo = the museum
• la malnovan bildon = the old picture

Unlike English, Esperanto has only one article form: la. It does not change for gender, number, or case.

The ending -as marks the present tense in Esperanto.

So konservas means keeps, preserves, or maintains, depending on context.

Examples of verb endings:

• -as = present
• -is = past
• -os = future
• -us = conditional
• -u = command/wish
• -i = infinitive

So:

• konservi = to preserve / to keep
• konservas = preserves / keeps

The -n ending marks the direct object in Esperanto. The direct object is the thing directly affected by the action.

In this sentence:

• La muzeo = the museum → the subject, doing the action
• konservas = preserves
• la malnovan bildon = the old picture → the object, receiving the action

So bildon has -n because it is what the museum preserves.

Because adjectives must agree with the nouns they describe.

bildon is:

• singular
• direct object (-n)

So the adjective must match:

• malnova bildo = an old picture
• malnovan bildon = an old picture as a direct object

Agreement means the adjective takes the same grammatical endings for number and object marking.

It comes from:

• nova = new
• mal- = opposite prefix

So:

• malnova = old

This is a very common Esperanto pattern. The prefix mal- creates the opposite meaning.

Examples:

• bona = good → malbona = bad
• granda = big → malgranda = small
• juna = young → maljuna = old

Because muzeo is the subject, not the direct object.

In Esperanto, the -n ending is usually used for the direct object, not the subject.

So:

• La muzeo = the museum → does the action
• la malnovan bildon = the old picture → receives the action

That is why only bildon gets -n.

Yes. Because Esperanto marks the direct object with -n, word order is more flexible than in English.

These all mean essentially the same thing:

• La muzeo konservas la malnovan bildon.
• La malnovan bildon konservas la muzeo.
• Konservas la muzeo la malnovan bildon.

However, the first version is the most neutral and easiest for learners: subject + verb + object.

It can mean picture, image, or sometimes representation, depending on context.

In a museum context, bildo often suggests a picture or image. If the meaning shown to the learner is picture, that is a perfectly natural understanding here.

To make nouns plural, Esperanto adds -j. Adjectives must agree with that too.

So:

• La muzeo konservas la malnovajn bildojn.
  = The museum preserves the old pictures.

Notice the endings:

• bildojn = plural object (-j
  • -n)
• malnovajn = adjective agreeing with a plural object

In Esperanto, adjectives end in -a.

So in this sentence:

• malnovan is the adjective
• bildon is the noun it describes

Base forms:

• malnova = old
• bildo = picture

Because bildon is a direct object, the adjective also takes -n, becoming malnovan.

Yes. Konservi often has the sense of preserve, conserve, or keep in good condition, not just possess.

So in a museum sentence, preserves is often a very natural translation, because museums protect and maintain old objects.
