Posa l'ampolla d'aigua a la nevera i el got sobre la taula.

Posa is the informal singular imperative of posar (to put / to place).

So here it means put!, said to one person in an informal way, like speaking to a friend, child, or someone you address as tu.

For comparison:

• posa = put! (to one person, informal)
• posi = put! (to one person, formal)
• poseu = put! (to more than one person, or formal plural)

Catalan often shortens el or la before a word beginning with a vowel or mute h. This is called elision.

So:

• la ampolla becomes l'ampolla

This works much like contractions in other languages:

• l'ampolla = the bottle

You will also see this in:

• l'aigua = the water
• l'home = the man
• l'escola = the school

d' is the shortened form of de before a vowel.

So:

• de + aigua → d'aigua

In l'ampolla d'aigua, the phrase literally means the bottle of water.

This is a very common structure in Catalan:

• una tassa de cafè = a cup of coffee
• un got d'aigua = a glass of water
• una ampolla de vi = a bottle of wine

Yes. Catalan very often uses a noun + de + noun structure where English may use a compound noun.

So English water bottle is commonly expressed as:

• ampolla d'aigua = bottle of water / water bottle

This is completely normal Catalan. English likes compound nouns more than Catalan does.

Here a indicates destination or location, and in this sentence it is best understood as into / in / to depending on the English translation.

So:

• Posa l'ampolla d'aigua a la nevera = Put the water bottle in / into the fridge

Catalan often uses a in places where English chooses between to, in, into, or on, depending on context.

The exact English wording depends on the action:

• with movement, English often prefers into
• with result/location, English may simply say in

Because the two location expressions are different:

• a la nevera = in / into the fridge
• sobre la taula = on the table

sobre specifically means on top of / over / on.

So the sentence uses:

• a for the fridge
• sobre for the table surface

This is natural because a bottle goes in the fridge, but a glass goes on the table.

Because Catalan, like English, can leave out a repeated verb when it is understood from the context.

So this sentence is really understood as:

• Posa l'ampolla d'aigua a la nevera i (posa) el got sobre la taula.

The second posa is omitted because it would be repetitive.

English does exactly the same thing:

• Put the bottle in the fridge and the glass on the table.

Yes, that is the natural interpretation.

The omitted verb from the first part carries over:

• Posa ... i (posa) el got sobre la taula

So the structure is:

• put the bottle in the fridge
• and put the glass on the table

A learner might briefly wonder whether sobre la taula could attach differently, but in normal usage the sentence is understood as two parallel commands.

Catalan generally uses definite articles more regularly than English in this kind of sentence.

Here:

• l'ampolla d'aigua = the water bottle
• la nevera = the fridge
• el got = the glass
• la taula = the table

This usually means the speaker has specific objects in mind, or the context makes them identifiable.

Using the articles here is completely normal and expected.

The basic pattern is:

• Posa — verb
• l'ampolla d'aigua — direct object
• a la nevera — location/destination
• i — and
• el got — second direct object
• sobre la taula — second location

So the full underlying structure is:

• Posa [object] [place] i [object] [place].

This is a very common and natural order in Catalan commands.

Yes. dins la nevera or dins de la nevera can also mean inside the fridge.

Possible versions include:

• a la nevera
• dins la nevera
• dins de la nevera

The original a la nevera is very natural and common.
Using dins makes the idea of inside a little more explicit.

No. Nevera is very common, but you may also hear frigorífic.

In everyday speech:

• nevera = fridge
• frigorífic = refrigerator

In many contexts they are interchangeable, though nevera often sounds more everyday and conversational.

The main change would be the imperative form of the verb posar.

Informal singular:

• Posa l'ampolla d'aigua a la nevera i el got sobre la taula.

Formal singular:

• Posi l'ampolla d'aigua a la nevera i el got sobre la taula.

Plural:

• Poseu l'ampolla d'aigua a la nevera i el got sobre la taula.

Everything else can stay the same.

Got usually means glass in the general sense of a drinking glass.

Related words:

• got = drinking glass
• copa = goblet / wine glass / stemmed glass
• vas = tumbler, cup, or vessel; in some contexts it overlaps, but got is the most straightforward everyday word here

So el got sobre la taula naturally suggests the drinking glass on the table.
