La dungito laboras ĉe la institucio.

La is the Esperanto definite article, meaning the.

So:

• la dungito = the employee
• la institucio = the institution

Esperanto often uses la much like English the. Also, Esperanto has no separate word for a/an. If you want to say an employee, you would usually just say dungito with no article.

Dungito is built from:

• dungi = to employ / to hire
• -it- = a participle element meaning someone who has undergone the action
• -o = noun ending

So dungito literally means a person who has been hired, which is why it means employee.

A useful comparison:

• dunganto = employer
• dungito = employee

In Esperanto, all present-tense verbs end in -as.

So:

• labori = to work
• laboras = works / is working

This ending does not change for different subjects:

• mi laboras = I work
• li laboras = he works
• la dungito laboras = the employee works

That is much simpler than English, because Esperanto verbs do not change for I/you/he/she/they.

Because -o is the standard noun ending in Esperanto.

So if a word is a noun, it normally ends in -o:

• dungito = employee
• institucio = institution

This makes parts of speech very easy to recognize. For example:

• labori = to work
• laboras = works
• laboro = work, labor

Ĉe often means at, by, with, or in the sphere of someone or something.

In this sentence, ĉe la institucio means something like:

• at the institution
• with the institution
• sometimes even for the institution, depending on context

It is very common in Esperanto to use ĉe for the place or organization where someone works, studies, stays, or is connected.

Good question. Both can be possible, but they are not exactly the same.

• ĉe la institucio focuses on association with the institution: the employee works at/with that institution.
• en la institucio focuses more on being physically in the institution or inside its premises.

So in a work-context sentence, ĉe is often the more natural choice if you mean employment or attachment to the organization, not just physical location.

There is no -n because la institucio is not the direct object here.

In this sentence:

• La dungito is the subject
• laboras is the verb
• ĉe la institucio is a prepositional phrase

After a preposition like ĉe, you normally do not use -n.

You would use -n for a direct object, for example:

• La dungito vidas la institucion. = The employee sees the institution.

Here institucion gets -n because it is the object of vidas.

Yes, Esperanto word order is fairly flexible, although the normal order is still subject–verb–other elements.

The basic sentence:

• La dungito laboras ĉe la institucio.

You could also say:

• Ĉe la institucio laboras la dungito.

That can sound more marked or stylistic, depending on context. Beginners should usually stick to the standard order unless they have a reason to emphasize something.

Ĉ is pronounced like ch in church.

So:

• ĉe sounds roughly like cheh

A rough pronunciation of the whole sentence is:

• la doon-GEE-to la-BOR-as cheh la in-stee-too-TSI-o

A few helpful points:

• Stress is always on the next-to-last syllable
• dungito → dun-GI-to
• laboras → la-BO-ras
• institucio → in-sti-tu-CI-o

Often yes, because it is a close cognate, but you should still pay attention to context.

Institucio can mean an institution in the broad sense: an organization, establishment, or formal body. Depending on context, English might sometimes translate it as:

• institution
• organization
• establishment

So the Esperanto word is familiar-looking, but the most natural English equivalent may vary.

Yes, it can. With organizations and workplaces, ĉe often covers the idea of being attached to that employer or workplace.

So in practice, laboras ĉe la institucio may be understood as:

• works at the institution
• works for the institution

If you specifically want to emphasize for the benefit of or on behalf of, Esperanto might use por in other contexts, but for ordinary employment, ĉe is very common and natural.
