La kudrilo estas apud la pinglo.

La is the Esperanto definite article, equivalent to English the.

So:

• la kudrilo = the needle
• la pinglo = the pin

Esperanto has only one definite article: la. It does not change for gender, case, or number.

Because both nouns are definite: the needle and the pin.

In Esperanto, if both things are specific, each noun normally gets its own la:

• La kudrilo estas apud la pinglo.

This is just like English The needle is next to the pin.

The ending -o marks a noun in Esperanto.

So:

• kudrilo = a noun
• pinglo = a noun

This is one of the most basic Esperanto patterns:

• -o = noun
• -a = adjective
• -e = adverb
• -i = infinitive verb

Kudrilo can be broken down like this:

• kudr- = sew
• -il- = tool or instrument
• -o = noun

So kudrilo literally means a sewing tool, which gives needle.

This is a very common Esperanto word-building pattern. For example:

• tranĉi = to cut
• tranĉilo = knife, cutting tool

Yes. Even if the meaning has already been given, a learner might notice that Esperanto uses two different words here.

• kudrilo = needle
• pinglo = pin

So the sentence is contrasting two different small pointed objects.

Estas is the present tense of esti, meaning to be.

So:

• estas = is / are / am

In this sentence:

• La kudrilo estas apud la pinglo.
• The needle is next to the pin.

Esperanto verbs do not change according to the subject. So:

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

The form estas stays the same.

Apud means next to, beside, or by.

It shows position near something.

So:

• apud la pinglo = next to the pin

It usually suggests physical closeness.

Both can sometimes be translated with English words like at, by, or near, but they are not exactly the same.

• apud = beside, next to, right by
• ĉe = at someone’s place, at, with, in the vicinity of

So in this sentence, apud is better because it clearly describes one object being beside another object.

Because there is no direct object here, and the sentence describes location, not motion toward something.

Breakdown:

• La kudrilo is the subject.
• estas is the verb.
• apud la pinglo is a prepositional phrase showing location.

So no accusative -n is needed.

A learner might expect la pinglon, but that would be wrong here.

Not in this exact sentence.

Since estas describes a state or location, not movement, the sentence stays:

• La kudrilo estas apud la pinglo.

If you changed the whole sentence to one involving placement or movement, you might see -n somewhere else, but not because of estas here.

For example:

• Mi metas la kudrilon apud la pinglo.
• I put the needle next to the pin.

Here kudrilon has -n because it is the direct object of metas.

The subject is la kudrilo.

That is the thing being talked about: the needle.

The rest tells us something about it:

• estas = is
• apud la pinglo = next to the pin

So the full structure is:

• La kudrilo = subject
• estas = verb
• apud la pinglo = location phrase

Yes, Esperanto word order is fairly flexible, though the basic order here is the most straightforward.

Standard order:

• La kudrilo estas apud la pinglo.

You could also say:

• Apud la pinglo estas la kudrilo.

That can sound a bit more like Next to the pin is the needle.

But for learners, the original version is the clearest and most neutral.

To make the nouns plural, add -j:

• kudrilo → kudriloj
• pinglo → pingloj

So:

• La kudriloj estas apud la pingloj.
• The needles are next to the pins.

Notice that la and estas do not change.

A helpful rough guide is:

• La = lah
• kudrilo = koo-DREE-lo
• estas = ES-tahs
• apud = ah-POOD
• la = lah
• pinglo = PEEN-glo

Stress in Esperanto is always on the second-to-last syllable:

• ku-DRI-lo
• ES-tas
• a-PUD
• PIN-glo

No. Kudrilo and pinglo are just nouns; they are not grammatically masculine or feminine.

Esperanto nouns do not have inherent grammatical gender the way nouns do in many European languages. So nothing in this sentence changes because of gender.

Not exactly.

The Esperanto sentence has la kudrilo, which means the needle, not a needle.

If you wanted a needle, Esperanto often just leaves out the article:

• Kudrilo estas apud la pinglo.

However, article use can depend on context, and in many beginner examples la is used because the objects are understood to be specific.
