La borilo estas apud la brikoj.

La is the Esperanto definite article, meaning the.

So:

• la borilo = the drill
• borilo = a drill or just drill in a general sense

Esperanto has only one article, la, and it does not change for plural, gender, or case in normal use.

Yes. Borilo is a built word.

It comes from:

• bor- = the idea of drilling
• -il- = tool or instrument
• -o = noun ending

So borilo literally means a tool for drilling.

This is very common in Esperanto. The ending -il- often creates names of tools:

• tranĉi = to cut → tranĉilo = knife, cutting tool
• skribi = to write → skribilo = writing instrument

Estas is the present-tense form of esti, which means to be.

So:

• mi estas = I am
• vi estas = you are
• li/ŝi estas = he/she is
• ili estas = they are

Unlike English, Esperanto uses the same present-tense form estas for all persons.

In this sentence, La borilo estas... means The drill is...

Apud is a preposition meaning beside, next to, or by.

In this sentence:

• apud la brikoj = beside the bricks

It shows location relative to something else.

Some similar location words are:

• sur = on
• sub = under
• en = in
• antaŭ = in front of
• malantaŭ = behind
• apud = next to

The ending -j marks the plural in Esperanto.

So:

• briko = brick
• brikoj = bricks

Since the sentence refers to more than one brick, Esperanto adds -j.

The accusative ending -n is usually used for a direct object, and sometimes for direction.

But in La borilo estas apud la brikoj, there is no direct object. The sentence is just describing where something is.

• La borilo = the subject
• estas apud la brikoj = tells its location

Because this is a location statement, not an action done to something, no noun needs -n here.

Yes, to some extent.

Esperanto word order is fairly flexible, although subject + verb + rest is the most neutral pattern.

So the normal version is:

• La borilo estas apud la brikoj.

But you might also see:

• Apud la brikoj estas la borilo.

That puts more focus on the location first, like Beside the bricks is the drill.

The original sentence is the most straightforward version for learners.

Because the sentence is talking about specific bricks, not bricks in general.

• apud brikoj would sound odd or incomplete in most normal contexts
• apud la brikoj = beside the bricks

Just as in English, whether you use the depends on whether the listener can identify what things you mean.

Not exactly.

Apud usually means right by, next to, or beside—normally quite close.

If you want a looser idea of near, Esperanto often uses:

• proksime de = near, close to

So:

• apud la brikoj = beside the bricks
• proksime de la brikoj = near the bricks

In many situations they may both work, but apud usually suggests more immediate closeness.

A simple pronunciation guide is:

• La = lah
• borilo = boh-REE-loh
• estas = ESS-tahs
• apud = ah-POOD
• la = lah
• brikoj = BREE-koy

A few useful pronunciation notes:

• Stress is always on the second-to-last syllable:
  • bo-RI-lo
  • ES-tas
  • a-PUD
  • BRI-koj
• j sounds like English y
  • so brikoj sounds like BREE-koy

It breaks down like this:

• La borilo = noun phrase, the subject
• estas = verb
• apud la brikoj = prepositional phrase showing location

So the pattern is:

subject + to be + location

This is one of the most basic and common sentence patterns in Esperanto.
