Eĉ se la lupago estas alta, la luanto restos.

Eĉ se means even if or even though, depending on context.

In this sentence, it introduces a concession: something is true despite another fact.

• Eĉ = even
• se = if

So Eĉ se la lupago estas alta literally means Even if the rent is high.

In real usage, eĉ se often overlaps with English even though, especially when the situation is presented as real rather than hypothetical.

La is Esperanto’s definite article, meaning the.

So:

• la lupago = the rent
• la luanto = the tenant

Esperanto uses la much like English the. If the sentence is talking about a specific rent and a specific tenant, la is natural.

Unlike English, Esperanto has only one definite article:

• no a/an
• no different forms like the / this / that

So la stays the same regardless of gender, number, or case.

Lupago is a compound word.

It can be understood as:

• lu- = related to renting
• pago = payment

So lupago literally means something like rental payment, which in normal English is rent.

Esperanto often builds words this way, by combining meaningful parts. That is one of the language’s most useful features.

Related words include:

• lui = to rent
• luanto = tenant
• luigi = to rent out, to let
• luiganto = landlord / person who rents something out

Luanto means tenant, and it is built very regularly:

• lu- = rent
• -ant- = present active participant, someone doing the action
• -o = noun ending

So luanto literally means a person who is renting.

This is a very common Esperanto pattern:

• lernanto = student, learner = someone learning
• parolanto = speaker = someone speaking
• laboranto = worker = someone working

So if you know the endings, words like this become easy to decode.

It is alta because it is a predicate adjective after estas.

In Esperanto, adjectives agree with nouns in number and case, but here alta is not directly modifying a noun inside a noun phrase. It is describing la lupago through the verb estas.

So:

• la lupago estas alta = the rent is high

You do not use the accusative -n here, because there is no direct object.

Compare:

• alta lupago = high rent
• la lupago estas alta = the rent is high

Both use alta, not altan.

The ending -os marks the future tense in Esperanto.

So:

• restas = stays / remains
• restis = stayed / remained
• restos = will stay / will remain

Here, la luanto restos means the tenant will stay or will remain.

Esperanto verb endings are very regular:

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

It can mean both, depending on context.

• resti = to remain
• resti = to stay

In this sentence, la luanto restos could be translated as:

• the tenant will stay
• the tenant will remain

English chooses between stay and remain based on style and context, but Esperanto uses resti naturally for both ideas.

Because there is no direct object.

Let’s look at the structure:

• la lupago estas alta
  Here, la lupago is the subject, and alta is a predicate adjective.

• la luanto restos
  Here, la luanto is also the subject, and restos is an intransitive verb.

Since neither clause has a direct object, there is no need for -n.

Often, yes.

Kvankam means although or though.

So a similar sentence could be:

• Kvankam la lupago estas alta, la luanto restos.

That would mean essentially the same thing: Although the rent is high, the tenant will stay.

A small nuance:

• eĉ se is literally even if, and can sometimes sound a bit more like a concessive condition.
• kvankam is more directly although / though.

In many everyday sentences, both are acceptable.

Yes, Esperanto word order is fairly flexible, though the normal order here is very natural.

This sentence uses a common structure:

• subordinate clause first: Eĉ se la lupago estas alta
• main clause second: la luanto restos

You could also say:

• La luanto restos, eĉ se la lupago estas alta.

That means the same thing.

Because Esperanto marks grammar clearly, word order can be moved more freely than in English, but the most neutral order is usually the easiest for learners to follow.

Because luanto is the person renting something for their own use: the tenant.

Esperanto distinguishes the roles clearly:

• luanto = tenant
• luiganto = landlord / lessor / person renting something out

The difference is the suffix:

• -ant- = someone doing the base action
• -ig- = causing or making something happen

So:

• lui = to rent
• luigi = to cause to be rented, to rent out

That is why luiganto is the one who lets the property, while luanto is the one who occupies it as a renter.
