La deponejo ricevas metalon kaj vitron.

The -n ending marks the direct object in Esperanto. That means these are the things being received.

• ricevas = receives
• metalon = metal
• vitron = glass

So La deponejo ricevas metalon kaj vitron means that the depot is receiving those materials. In English, word order usually shows this, but Esperanto often uses the -n ending instead.

In Esperanto, all nouns end in -o.

So:

• deponejo = a depot / storage place / collection point

The final -o tells you it is a noun. This is one of the most regular parts of Esperanto grammar.

The suffix -ej- means place.

So deponejo can be broken down like this:

• depon- = store, deposit
• -ej- = place
• -o = noun ending

So deponejo literally means something like a place for depositing or storing things. Learning common suffixes like -ej- is very helpful in Esperanto because they let you understand many words quickly.

Because la applies to the noun phrase la deponejo only.

The sentence structure is:

• La deponejo = the depot
• ricevas = receives
• metalon kaj vitron = metal and glass

There is no need to repeat la before metalon and vitron unless you specifically want to say the metal and the glass. As written, it means metal and glass in a general sense.

In Esperanto, singular can be used for a material or substance in a general sense.

So:

• metalon = metal
• vitron = glass

This is similar to English when we talk about materials as mass nouns, as in We recycle metal and glass. If you wanted to talk about multiple separate objects, you might use plurals, but here the sentence is about the materials in general.

Ricevas is the present-tense form of the verb ricevi, meaning to receive.

Esperanto verb endings are very regular:

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

So:

• ricevi = to receive
• ricevas = receives / is receiving

In Esperanto, verbs do not change depending on the subject. So:

• mi ricevas
• vi ricevas
• la deponejo ricevas

All use the same -as ending.

Yes, Esperanto allows more flexible word order than English because the -n ending shows the object.

For example, these would still be understandable:

• Metalon kaj vitron ricevas la deponejo.
• Ricevas la deponejo metalon kaj vitron.

However, the most neutral and common order is:

• La deponejo ricevas metalon kaj vitron.

That is the clearest form for most learners.

Yes, in this sentence kaj simply means and.

It joins the two objects:

• metalon kaj vitron = metal and glass

This is very straightforward. Kaj is one of the basic coordinating conjunctions in Esperanto.

Yes, vitro means glass as a material. Depending on context, Esperanto can also use related words for glass objects.

In this sentence, because it appears with metalon and in the context of a deponejo, the meaning is clearly the material glass, not a drinking vessel.

Context usually makes this clear, just as in English.

A rough pronunciation guide is:

• La = lah
• deponejo = deh-po-NEH-yo
• ricevas = ree-TSEH-vahs
• metalon = meh-ta-LON
• kaj = kai
• vitron = VEE-tron

A few useful pronunciation points:

• j sounds like English y
• c sounds like ts
• stress is always on the second-to-last syllable

So:

• de-po-NE-jo
• ri-CE-vas
• me-ta-LON
• VI-tron

Because ricevas already contains the full idea of receives / is receiving. Esperanto verbs do not need an extra helping verb in simple present sentences.

So:

• La deponejo ricevas metalon kaj vitron
  already means The depot receives metal and glass or The depot is receiving metal and glass, depending on context.

There is no need to add a separate word for is here.
