La komisiono kontrolas la dentoklinikon.

The -n ending marks the direct object in Esperanto. It shows which thing is being acted on.

• La komisiono = the commission/committee → the subject
• kontrolas = checks/inspects
• la dentoklinikon = the dental clinic → the thing being checked

So dentokliniko becomes dentoklinikon because it is the object of the verb.

Because komisiono is the subject, not the object. In this sentence, the commission is doing the action, so it stays in its basic form:

• komisiono = subject
• dentoklinikon = object

In Esperanto, the -n is normally used for the direct object, not for the subject.

The ending -as marks the present tense in Esperanto.

So kontrolas means checks, is checking, or sometimes does check, depending on context.

Esperanto verb endings are very regular:

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

La is the Esperanto definite article, meaning the.

So:

• la komisiono = the commission
• la dentoklinikon = the dental clinic

Unlike English, Esperanto has only one definite article: la. It does not change for gender, number, or case. Even when the noun gets -n, the article stays la.

Yes, it is very similar in meaning. Komisiono usually means a commission, committee, or official group assigned to examine, supervise, or manage something.

A learner may notice that many Esperanto words look familiar because they come from international roots. Komisiono is one of them.

It is a compound word:

• dento = tooth
• kliniko = clinic
• dentokliniko = dental clinic

Then the object ending -n is added:

• dentokliniko → dentoklinikon

This kind of word-building is very common in Esperanto. You can often understand long words by breaking them into meaningful pieces.

Esperanto often uses compounds where English might use either a compound noun or an adjective + noun.

So both structure and meaning are worth noticing:

• dentokliniko = dental clinic
• literally, something like tooth-clinic

You may also see adjective-based expressions in Esperanto, but compounds are extremely common and natural.

Yes, Esperanto word order is fairly flexible because the -n ending helps show the object.

For example, these mean basically the same thing:

• La komisiono kontrolas la dentoklinikon.
• La dentoklinikon kontrolas la komisiono.

Because dentoklinikon has -n, we still know it is the object. However, the first version is the most neutral and natural for beginners: subject + verb + object.

Esperanto pronunciation is very regular, and stress is always on the second-to-last syllable.

• komisiono → ko-mi-si-O-no
• kontrolas → kon-TRO-las
• dentoklinikon → den-to-kli-NI-kon

A few useful pronunciation notes:

• o is like a pure o
• i is like ee
• e is like e in met
• every letter is pronounced clearly

In Esperanto, kontroli usually means to check, inspect, verify, or examine, not usually to control in the English sense of ruling or directing something.

So La komisiono kontrolas la dentoklinikon is understood as the commission checks/inspects the dental clinic.

This is a useful false-friend warning for English speakers.

The dictionary forms are:

• la = the
• komisiono = commission / committee
• kontroli = to check / inspect
• la = the
• dentokliniko = dental clinic

In the sentence:

• kontroli becomes kontrolas because it is present tense
• dentokliniko becomes dentoklinikon because it is the direct object

In Esperanto, nouns normally end in -o.

So:

• komisiono = noun
• dentokliniko = noun

This is one of the most helpful regular patterns in Esperanto:

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

Because dentokliniko ends in -o, you can immediately identify it as a noun.

Yes. In Esperanto, plural nouns take -j, and if a plural noun is also a direct object, it takes both -j and -n, giving -jn.

Examples:

• La komisionoj kontrolas la dentoklinikon. = The commissions check the dental clinic.
• La komisiono kontrolas la dentoklinikojn. = The commission checks the dental clinics.

So Esperanto endings stack in a very regular way.
