La posedanto volas luigi la ĉambron.

The -n marks the direct object.

In La posedanto volas luigi la ĉambron, the thing being rented out is the room, so ĉambro becomes ĉambron.

• ĉambro = room
• ĉambron = room (as the direct object)

This is one of the most important endings in Esperanto. It often tells you what receives the action, even if the word order changes.

In Esperanto, the infinitive already includes that idea. The infinitive ending is -i.

So:

• voli = to want
• luigi = to rent out / to let

That means volas luigi literally means something like wants rent out, but in correct English we translate it as wants to rent out.

Esperanto does not use a separate word like English to before the infinitive.

This is a very natural question, because luigi is more specific than lui.

• lui = to rent / hire
• luigi = to cause to be rented, so to rent out, to let, to lease out

The suffix -ig- often has a causative meaning: it means to make something be in a certain state or to cause an action.

So:

• lui la ĉambron = to rent the room
• luigi la ĉambron = to rent out the room

In this sentence, the owner is not the one renting it for their own use. The owner wants someone else to rent it, so luigi is the right choice.

Posedanto is made from:

• posed- = possess / own
• -ant- = present active participle, meaning one who is doing
• -o = noun ending

So posedanto literally means one who possesses/owns.

That is why it means owner or possessor.

This kind of word-building is very common in Esperanto, and once you get used to it, it becomes very helpful.

Examples:

• lernanto = learner, student
• instruanto = teacher (literally one who teaches)
• parolanto = speaker (one who speaks)

Because Esperanto uses la for the, and both nouns are definite here:

• la posedanto = the owner
• la ĉambron = the room

Using la twice is completely normal. English does the same thing:

• The owner wants to rent out the room.

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

Yes, to some extent.

The normal order here is:

• La posedanto = subject
• volas luigi = verb phrase
• la ĉambron = object

So the sentence is in a standard subject–verb–object pattern.

Because ĉambron has the -n ending, Esperanto can sometimes change word order without losing clarity. For example, La ĉambron la posedanto volas luigi is still understandable, because -n shows that ĉambron is the object.

However, for learners, the ordinary order is best unless there is a special reason to emphasize something.

It is a correct and clear word, but depending on context, Esperanto speakers may also use other words.

For example:

• posedanto = possessor / owner
• proprietulo = proprietor / owner
• sometimes other context-specific words are possible

Posedanto is very understandable and transparently built, so it is a good word for learners to know.

Because -as is the present-tense ending in Esperanto.

• volas = wants
• volis = wanted
• volos = will want

So the sentence describes a present situation: the owner wants to rent out the room.

The infinitive luigi does not show tense by itself here; the tense is carried by volas.

Yes, that is part of the nuance of luigi.

Because -ig- has a causative sense, luigi can suggest causing the room to be rented, which in natural English is usually just rent out or let.

So depending on context, the idea may be:

• the owner wants to offer the room for rent
• the owner wants someone to rent the room
• the owner wants the room to be rented

In ordinary usage, wants to rent out the room is the most natural translation.

In Esperanto, stress almost always falls on the second-to-last syllable.

So:

• po-se-DAN-to
• VO-las
• lu-I-gi
• la ĉam-BRON

This rule is very regular, which makes pronunciation much easier than in English.

Ĉ is pronounced like English ch in church.

So ĉambro sounds roughly like CHAM-bro.

A few useful related letters:

• ĉ = ch as in church
• ŝ = sh as in shoe
• ĵ = the sound in measure
• c = ts as in cats

So ĉambron begins with that clear ch sound.

It helps to recognize both the whole word and its parts.

For example:

• posedanto = posed- + -ant- + -o
• luigi = lu- + -ig- + -i
• ĉambron = ĉambr- + -o + -n

This is one of the strengths of Esperanto: many words are built very regularly, so instead of memorizing everything as separate vocabulary, you can often analyze them.

That said, you will still want repeated exposure so that common forms become automatic.
