Alia ekzemplero estas havebla.

Alia means another or other.

In Alia ekzemplero estas havebla, it most naturally means another copy is available.

A learner might confuse alia with words like nova (new), but they are different:

• alia ekzemplero = another copy / a different copy
• nova ekzemplero = a new copy

So alia focuses on it being a different one, not necessarily a newly made one.

Ekzemplero usually means copy, specimen, or individual example of an item.

In many everyday contexts, it is best translated as copy, especially for things like books, documents, or products.

Even though it looks related to ekzemplo (example), ekzemplero is not usually the ordinary word for an illustrative example in a sentence or explanation. It often refers to an actual instance or copy of something.

So here:

• Alia ekzemplero = another copy / another экземпляр-type item

Estas is the present tense of esti, meaning to be.

So the structure is:

• Alia ekzemplero = the subject
• estas = is
• havebla = available

Literally: Another copy is available.

This is a very normal Esperanto sentence pattern.

You may also see a shorter version:

• Alia ekzemplero haveblas.

That means essentially the same thing. In that version, haveblas works like is available all by itself.

Havebla means available, obtainable, or more literally able to be had.

It is built from:

• hav- = have
• -ebl- = possible / able to be
• -a = adjective ending

So:

• havebla = possible to have = available

This is a very Esperanto-style word formation. Once you know the parts, the meaning becomes quite transparent.

Compare:

• manĝebla = edible = able to be eaten
• videbla = visible = able to be seen
• havebla = available = able to be had

Because there is no direct object here.

In Alia ekzemplero estas havebla:

• alia ekzemplero is the subject
• havebla is a predicate adjective after estas

The accusative -n is mainly used for direct objects and some other special uses, but not for the subject of esti and not for the adjective describing that subject.

So:

• Alia ekzemplero estas havebla. = correct

You would not add -n to ekzemplero or havebla here.

Because the sentence is singular.

• alia = another / other
• ekzemplero = copy

So it refers to one copy.

If you wanted the plural, you would use -j on both the noun and its adjective:

• Aliaj ekzempleroj estas haveblaj. = Other copies are available.

Notice the agreement:

• alia → aliaj
• ekzemplero → ekzempleroj
• havebla → haveblaj

Adjectives in Esperanto agree with the noun they describe in number and case.

Because Esperanto has no indefinite article.

English says:

• Another copy is available
• A copy is available

Esperanto simply says:

• Alia ekzemplero estas havebla
• Ekzemplero estas havebla

Esperanto does have a definite article, la, for the, but it does not have a separate word for a/an.

So the lack of an article here is completely normal.

Yes, but it would mean something more specific.

• Alia ekzemplero estas havebla = Another copy is available
• La alia ekzemplero estas havebla = The other copy is available

Adding la makes the noun phrase definite. It suggests that the speaker and listener already know which other copy is being talked about.

So without la, the sentence is more general. With la, it points to a specific one.

Yes, Esperanto word order is fairly flexible, though the basic order here is the most natural.

Standard order:

• Alia ekzemplero estas havebla.

Other possible orders include:

• Havebla estas alia ekzemplero.
• Estas havebla alia ekzemplero.

These are grammatically possible, but they may sound more marked or stylistic depending on context.

For a learner, the original order is the safest and most neutral.

No. Esperanto has a few ways to express this idea, depending on context.

For example:

• havebla = available, obtainable
• disponebla = available, at one’s disposal

In many contexts, both could work, but they are not always identical in nuance.

• Alia ekzemplero estas havebla.
  This emphasizes that another copy can be had or obtained.

• Alia ekzemplero estas disponebla.
  This can sound more like it is available for use or at hand.

For many learners, havebla is a very clear and logical formation.

Sometimes yes, depending on what you mean.

• kopio usually means copy in a more direct sense
• ekzemplero often means an individual copy / specimen / instance

If you are talking about a physical or countable copy of a book, magazine, or document, both may be possible in some contexts. But ekzemplero often sounds especially natural for a copy/item of an edition or product.

So:

• Alia kopio estas havebla.
• Alia ekzemplero estas havebla.

Both can be understandable, but ekzemplero may be the more idiomatic choice in some situations.

Almost, but not perfectly.

A very literal breakdown is:

• Alia = other / another
• ekzemplero = copy / specimen
• estas = is
• havebla = able to be had

So the literal sense is:

• Another copy is able to be had

Natural English would normally be:

• Another copy is available

This is a good example of how Esperanto word-building is often very logical, even when the best English translation uses a less literal word.
