La taula és a l'habitació, sota la finestra.

In standard Catalan, ser is very commonly used to say where something is located, especially in straightforward descriptions like this one: La taula és a l'habitació.

So for a learner, és is the normal and safe choice here.

You may also hear estar in some varieties or more colloquial speech, but és is perfectly standard in this sentence.

This is a very common question for English speakers.

In Catalan, a is often used where English uses in, at, or to, depending on context. So a l'habitació can naturally mean in the room.

Catalan does have en, but with locations, modern standard Catalan very often prefers a:

• és a casa
• és a l'escola
• és a l'habitació

So even though English uses in, Catalan commonly uses a here.

Because the article la becomes l' before a word that begins with a vowel sound, or with a silent h.

So:

• la taula
• la finestra
• l'habitació

This is called elision. It works much like French in forms such as l'hôtel.

No. In Catalan, the h in habitació is silent.

That is why the article elides:

• l'habitació

You pronounce it as if the word began with the vowel:

• a-bi-ta-ci-ó (roughly)

You usually learn the gender together with the noun, but there are some useful patterns:

• taula ends in -a, which is very often feminine.
• finestra also ends in -a, so feminine is not surprising.
• habitació ends in -ció, and nouns ending in -ció are typically feminine.

That is why the sentence uses:

• la taula
• l'habitació
• la finestra

A good habit is to memorize nouns with their article, not by themselves.

Normally, no. In Catalan, you usually keep the definite article with specific countable nouns like these.

So Catalan says:

• la taula
• l'habitació
• la finestra

Omitting the article would sound wrong in this sentence.

This is one place where Catalan is less flexible than English, which sometimes drops articles more easily.

Sota means under or beneath.

So:

• sota la finestra = under the window

You can also hear sota de la finestra. Both are used, and both are understandable. In a simple sentence like this, sota la finestra is very natural and concise.

It describes the table.

The idea is:

• the table is in the room
• more specifically, it is under the window

So both location phrases refer to la taula:

• a l'habitació
• sota la finestra

The comma helps show that the second phrase is extra location information about the table, not a description of the room.

Not always strictly necessary, but it is helpful here.

The comma creates a small pause and makes the sentence easier to read:

• La taula és a l'habitació, sota la finestra.

It signals that sota la finestra is an added detail about the table's location.

Without the comma, the sentence would still usually be understood, but the comma makes the structure clearer.

No, Catalan allows some flexibility, but this order is the most neutral and natural:

• La taula és a l'habitació, sota la finestra.

You can move parts around for emphasis, for example:

• Sota la finestra, la taula és a l'habitació.

But that sounds more marked and less neutral. For a basic descriptive sentence, the original word order is the best model to follow.
