La dentisto parolis kun la komisiono.

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

So:

• la dentisto = the dentist
• la komisiono = the committee / the commission

Esperanto uses la separately before each noun when each noun is definite. You do not use one la to cover both words unless they are part of the same noun phrase.

Also, la never changes form. It is always just la.

The ending -o marks a noun in Esperanto.

So:

• dentisto is a noun
• komisiono is a noun

This is one of the most basic and useful Esperanto patterns:

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

Because Esperanto is very regular, seeing -o immediately tells you that the word is functioning as a noun.

Yes. Esperanto words are often built from meaningful pieces.

dentisto can be broken down as:

• dent- = tooth
• -ist- = a person professionally associated with something
• -o = noun ending

So dentisto literally means something like tooth-professional, which gives dentist.

The suffix -ist- appears in many words, for example:

• pianisto = pianist
• artisto = artist
• ĵurnalisto = journalist

The ending -is marks the past tense in Esperanto.

So:

• paroli = to speak / to talk
• parolas = speaks / is speaking / talks
• parolis = spoke / talked
• parolos = will speak / will talk

In this sentence, parolis tells you the action happened in the past: spoke or talked.

A very useful rule is that Esperanto verb endings are always regular:

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

Yes. Kun means with.

So parolis kun la komisiono means spoke with the committee.

This expresses conversation or interaction together with someone. It is very close to English talk with.

A related point:

• paroli kun iu = to speak with someone
• paroli al iu = to speak to someone

In real usage, both can be correct, but they emphasize slightly different things:

• kun suggests a two-way interaction
• al suggests direction toward a listener

Because la komisiono is not the direct object here.

The accusative ending -n is used for the direct object, but in this sentence the noun is inside a prepositional phrase:

• kun la komisiono = with the committee

After a preposition like kun, you normally do not add -n.

So this is correct:

• La dentisto parolis kun la komisiono.

Not:

• La dentisto parolis kun la komisionon.

The kun already shows the relationship, so accusative is unnecessary here.

Yes, Esperanto word order is fairly flexible, although the basic order is often subject–verb–other elements, as in this sentence.

Standard order:

• La dentisto parolis kun la komisiono.

You could also say:

• Kun la komisiono parolis la dentisto.

That might sound more marked or stylistically different, perhaps emphasizing with the committee.

Because Esperanto has clear endings and prepositions, word order can move around more freely than in English. Still, the most neutral and beginner-friendly order is usually the one given.

It can mean either, depending on context.

Esperanto often uses one word where English may choose between two close translations. So komisiono can refer to a group appointed for some task, and English might translate it as:

• committee
• commission

The exact English choice depends on the situation, not on a different Esperanto form here.

Not necessarily.

By itself, dentisto does not tell you the person’s sex. In modern Esperanto usage, it can be neutral unless context says otherwise.

If you specifically want to indicate a female dentist, you may see:

• dentistino = female dentist

Traditionally, some speakers treated words like dentisto as more male-default in certain contexts, but many learners and speakers today understand them more neutrally unless a feminine suffix is added or context makes it clear.

So from this sentence alone, you should not assume the dentist was male.

A rough pronunciation guide is:

la den-TIS-to pa-RO-lis kun la ko-mi-si-O-no

A few useful pronunciation points:

• c in Esperanto sounds like ts
• s always sounds like s, never like z
• stress is always on the second-to-last syllable

So:

• dentisto → den-TIS-to
• parolis → pa-RO-lis
• komisiono → ko-mi-si-O-no

That regular stress pattern is one of the nice things about Esperanto.

Yes. In this sentence, both are natural.

• The dentist spoke with the committee.
• The dentist talked with the committee.

Esperanto paroli covers both speak and talk in many contexts. The best English choice depends on style and tone, not on a grammar difference in the Esperanto sentence.
