Se nia celo restos klara, ni povos fari la duan paŝon sen tro da streso.

Se means if. It introduces a condition.

So:

• Se nia celo restos klara = If our goal remains clear
• ni povos fari la duan paŝon = we will be able to take/make the second step

This is a very common sentence pattern in Esperanto:

• Se ... , ...
• If ... , ...

Resti means to remain or to stay, while esti means to be.

So:

• estos klara = will be clear
• restos klara = will remain clear / will stay clear

Using restos emphasizes that the goal is already clear, and the speaker wants that clarity to continue.

Restos is the future tense of resti.

Esperanto verb endings are very regular:

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

So:

• restas = remains
• restis = remained
• restos = will remain

Klara is an adjective meaning clear.

It matches celo because celo is:

• singular
• not accusative
• the subject of the clause

So the adjective also stays singular and without -n:

• celo klara = a clear goal
• nia celo restos klara = our goal will remain clear

If the noun were plural, the adjective would also be plural:

• niaj celoj restos klaraj = our goals will remain clear

Because nia celo is the subject of the clause, not the direct object.

In Esperanto, the direct object usually gets -n, but the subject does not.

Here:

• nia celo = the thing doing the remaining
• so it stays nominative: nia celo

Compare:

• Nia celo restos klara. = Our goal will remain clear.
• Ni klarigos nian celon. = We will clarify our goal.

In the second sentence, nian celon is the object, so it gets -n.

Also remember that possessives like nia behave like adjectives, so they agree with the noun when needed.

Because Esperanto often uses the tense that directly matches the meaning.

In English, we usually say:

• If our goal remains clear, we will be able...

Even though the first part refers to the future, English often uses the present after if.

Esperanto is freer to use the future in that clause when the meaning is genuinely future:

• Se nia celo restos klara, ni povos...

This is completely natural and clear in Esperanto.

Povi means can / to be able to.

So:

• povos = will be able to
• fari = to do / to make

Together:

• ni povos fari = we will be able to do / make

In this sentence, fari la duan paŝon is best understood as take the second step or make the second move/step.

Even though fari literally means do/make, Esperanto often uses it in places where English would use a more specific verb.

This phrase shows both the definite article and the accusative.

1. la

La means the.

2. duan

dua means second.
It becomes duan because it modifies a direct object.

3. paŝon

paŝo means step.
It becomes paŝon because it is the direct object of fari.

So:

• la dua paŝo = the second step
• fari la duan paŝon = to take/make the second step

Both the adjective and the noun take -n because they are part of the direct object phrase.

Because adjectives agree with the nouns they describe in Esperanto.

Since paŝon is:

• singular
• accusative

the adjective must match it:

• dua paŝo = second step
• duan paŝon = second step as a direct object

If it were plural, both words would change:

• la duaj paŝoj = the second steps
• la duajn paŝojn = the second steps as direct object

It breaks down like this:

• sen = without
• tro = too much / excessively
• da = of, used after quantity expressions
• streso = stress

So literally it is something like:

• without too much of stress

In natural English, that becomes:

• without too much stress
• without excessive stress

Because da is used after words that express quantity.

Common quantity words that often use da include:

• multe da = a lot of
• iom da = some
• sufiĉe da = enough
• tro da = too much / too many

So:

• tro da streso = too much stress

This is a very common Esperanto structure.

Because sen is a preposition, and nouns after ordinary prepositions do not take the accusative just because they follow a preposition.

So:

• sen streso = without stress
• sen tro da streso = without too much stress

The -n ending is mainly for direct objects or for certain motion/direction uses, not normally after a preposition like sen.

Also, in tro da streso, the noun after da does not take -n here.

Yes, it is understandable and natural.

Esperanto sometimes uses verbs in ways that are a little broader than the most common English equivalent. English says take a step, but Esperanto can say fari paŝon in the sense of making/taking a step in a process.

So fari la duan paŝon suggests moving on to the next stage.

Yes. Esperanto word order is fairly flexible, though the original order is the most straightforward.

For example, you could also say:

• Ni povos fari la duan paŝon, se nia celo restos klara.

This means the same thing:

• We will be able to take the second step if our goal remains clear.

The original version simply puts the condition first for emphasis.
