La luiganto luigas du apartamentojn.

La is the definite article, equivalent to English the.

So la luiganto means the landlord or more literally the renting-out person.

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

Luiganto is made from several parts:

• lu- / lui = to rent, hire, lease
• -ig- = a suffix meaning cause to or make happen
• -ant- = present active participle, meaning someone who is doing
• -o = noun ending

So:

• lui = to rent
• luigi = to cause something to be rented; in practice, to rent out / lease out
• luiganto = a person who rents something out

In a housing context, that is naturally the landlord.

This is a very common point of confusion.

• lui = to rent
  Depending on context, it can relate to renting something for use.
• luigi = to rent out, to lease out

The suffix -ig- often adds the idea of causing or making something happen.

So:

• luanto = tenant, renter
• luiganto = landlord, lessor

In this sentence, the subject is the person providing the apartments, so luigi is the correct verb idea.

Because luigas is the present-tense form of luigi.

Esperanto verb endings are very regular:

• -as = present
• -is = past
• -os = future
• -us = conditional
• -u = imperative / volitive
• -i = infinitive

So:

• luigi = to rent out
• luigas = rents out / is renting out

The sentence is therefore in the present tense.

Because it is both plural and the direct object.

Breakdown:

• apartamento = apartment
• apartamentoj = apartments
• apartamentojn = apartments as a direct object

The endings mean:

• -j = plural
• -n = accusative, usually marking the direct object

Since the apartments are the thing being rented out, they take -n.

Numbers in Esperanto do not take plural endings.

So:

• du apartamentoj = two apartments
• tri domoj = three houses

The noun itself shows plurality with -j, not the number.

In this sentence, apartamentojn has:

• -j for plural
• -n because it is the direct object

But du stays just du.

Esperanto normally has no indefinite article.

English distinguishes:

• a landlord
• the landlord

Esperanto only has a definite article, la. If there is no la, the noun is usually indefinite or unspecified.

So Esperanto can say:

• luiganto = a landlord / landlord
• la luiganto = the landlord

Here the sentence uses la, so the subject is definite: the landlord.

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

The normal order here is:

• La luiganto = subject
• luigas = verb
• du apartamentojn = object

But forms like these are also understandable:

• Du apartamentojn la luiganto luigas.
• Luigas la luiganto du apartamentojn.

The most neutral and standard order is still subject–verb–object, as in the original sentence.

Not always exactly, but often yes in context.

Literally, luiganto means someone who rents something out. That could be:

• a landlord
• a property owner
• a person leasing out a room, car, tool, etc.

In this sentence, because the object is du apartamentojn, the natural English translation is landlord or property owner renting out two apartments.

A rough pronunciation guide:

• luiganto → loo-ee-GAHN-to
• apartamentojn → ah-par-tah-MEN-toyn

A few useful points:

• Esperanto stress is always on the second-to-last syllable
• j sounds like English y
• oj sounds roughly like oy

So in apartamentojn, the ending -ojn is pronounced roughly oyn.

Because la marks something definite, and the speaker is identifying a specific landlord: the landlord.

But du apartamentojn does not need la unless you specifically mean the two apartments.

Compare:

• La luiganto luigas du apartamentojn. = The landlord rents out two apartments.
• La luiganto luigas la du apartamentojn. = The landlord rents out the two apartments.

So without la, du apartamentojn just means two apartments, not necessarily a specifically identified pair.
