La albumo restas en la studio.

In Esperanto, nouns end in -o. So albumo means album as a noun.

This makes word class very easy to recognize:

• albumo = album
• bela = beautiful
• restas = stays/remains

If you wanted the plural, you would add -j:

• albumoj = albums

La is the definite article in Esperanto, meaning the.

So:

• la albumo = the album
• la studio = the studio

Unlike English, Esperanto has only one definite article, la, and it does not change for gender, number, or case in ordinary use.

Resti is the infinitive, meaning to remain or to stay.

In a normal statement, Esperanto uses a finite verb form. -as marks the present tense:

• resti = to remain
• restas = remains / stays
• restis = remained
• restos = will remain

So La albumo restas en la studio means The album remains in the studio.

It can mean either, depending on context. Resti often means:

• to remain
• to stay

So this sentence could naturally be understood as:

• The album remains in the studio
• The album stays in the studio

Esperanto often has one verb covering meanings that English might split into different words.

The -n ending usually marks the direct object, but la studio here is not a direct object. It is part of a prepositional phrase:

• en la studio = in the studio

Because en already shows the relationship, studio normally stays without -n here.

So:

• La albumo restas = the album remains
• en la studio = in the studio

En la studio usually means in the studio in a location sense.

En la studion can be used when there is motion into that place. The -n can show direction.

Compare:

• La albumo estas en la studio. = The album is in the studio.
• Mi metas la albumon en la studion. = I put the album into the studio.

In your sentence, there is no movement into the studio, only location, so en la studio is correct.

En means in or inside.

So:

• en la studio = in the studio

It shows location. In this sentence, it tells you where the album remains.

It is a normal Esperanto word. Esperanto borrows many roots from European languages, but once borrowed, they follow Esperanto grammar.

So:

• studio = studio
• plural: studioj
• accusative: studion

Even if it looks familiar to an English speaker, it is still being used as a regular Esperanto noun.

Yes. Esperanto word order is fairly flexible, because endings help show grammatical roles.

For example, these are possible:

• La albumo restas en la studio.
• En la studio restas la albumo.

Both are grammatical, though the first is the most neutral and straightforward.

Because there is no direct object here, the sentence is already quite clear.

Because restas already carries the main verbal idea: remains/stays.

In English, learners sometimes expect an extra verb like is, but Esperanto does not need one here. The structure is simply:

• subject: La albumo
• verb: restas
• place phrase: en la studio

So the sentence is complete as it stands.

A simple approximate pronunciation is:

lah ahl-BOH-moh RES-tahs en lah stu-DEE-oh

A few helpful points:

• a is like a in father
• e is like e in bet, but often a bit clearer
• o is like o in for, but pure and steady
• stress usually falls on the second-to-last syllable

So:

• albumo → al-BU-mo
• restas → RES-tas
• studio → stu-DI-o

You would add -j to the noun, and the adjective too if there were one.

So:

• La albumoj restas en la studio.

Here:

• albumo = album
• albumoj = albums

The verb restas does not change for singular or plural.

Not exactly.

• La albumo estas en la studio. = The album is in the studio.
• La albumo restas en la studio. = The album remains/stays in the studio.

Estas simply states location.
Restas suggests continuing there, not moving away, or still being there.
