Не волнуйся, мы успеем на поезд, если выйдем пораньше.

Не волнуйся is the informal singular imperative of волноваться. It is used when speaking to one person in an informal way.

• не волнуйся = don’t worry to one friend, family member, child, etc.
• не волнуйтесь = either don’t worry to several people or to one person formally/politely

So this sentence sounds like the speaker is talking casually to one person.

The verb is волноваться, not just волновать. The ending -ся is part of the verb.

In many cases, -ся makes a verb reflexive, but in verbs like волноваться it is often best to learn the whole verb as a unit meaning to worry / to be anxious.

So:

• волноваться = to worry, to get anxious
• волнуйся = worry
• не волнуйся = don’t worry

You do not usually translate -ся literally here; it is simply part of the normal verb form.

It is future.

The infinitive is успеть, which is a perfective verb. In Russian, perfective verbs do not normally have a true present tense. Their present-looking forms actually refer to the future.

So:

• я успею = I will make it / I will be in time
• мы успеем = we will make it / we will be in time

That is why мы успеем means we’ll make it, not we make it.

This is a very common difference between English and Russian.

In Russian, when you talk about a real future condition, you normally use a future form after если:

• если выйдем пораньше = if we leave earlier

Literally, it may look like if we will leave earlier, but that is just how Russian grammar works. English and Russian handle future conditions differently.

So Russian can say:

• Если выйдем пораньше, успеем на поезд.

Both verbs refer to the future, and that is completely normal.

Because the sentence is about single completed actions/results in the future.

• успеть means to manage to be in time / to succeed in making it
• выйти means to go out / leave as one completed action

The idea is:

1. we leave earlier
2. as a result, we make it for the train

Perfective aspect is natural because the speaker is talking about one specific occasion and its result.

If you used imperfective forms, the meaning would shift toward process, repetition, or general habit. For example, something like если будем выходить пораньше, будем успевать на поезд would sound more like a repeated pattern: if we leave earlier regularly, we’ll keep making the train.

Поезд is in the accusative singular after на.

The expression успеть на поезд is a standard way to say to make the train / to catch the train in time.

A useful pattern to remember is:

• успеть на поезд
• успеть на автобус
• успеть на самолёт

Also, поезд is a masculine inanimate noun, so its accusative singular looks the same as the nominative singular:

• nominative: поезд
• accusative: поезд

So the form does not change, even though the case does.

Пораньше means earlier, often with the sense of a bit earlier or somewhat earlier.

Compared with раньше, пораньше often sounds:

• a little softer
• more conversational
• like a practical suggestion

So here:

• если выйдем раньше = if we leave earlier
• если выйдем пораньше = if we leave a bit earlier / if we head out earlier

In many situations, both work, but пораньше sounds very natural in everyday speech.

Russian often drops subject pronouns when the verb ending already makes the subject clear.

• успеем already tells you it means we will make it
• выйдем already tells you it means we will leave

So the sentence could also be:

• Не волнуйся, успеем на поезд, если выйдем пораньше.

The pronoun мы is included in the main clause mainly for emphasis or reassurance:

• мы успеем = we’ll make it

It gives the sentence a slightly more comforting, confident tone.

Yes. Russian word order is fairly flexible, as long as the grammar stays clear.

For example, these are all possible:

• Не волнуйся, мы успеем на поезд, если выйдем пораньше.
• Если выйдем пораньше, мы успеем на поезд.
• Мы успеем на поезд, если выйдем пораньше.

The original order is very natural in conversation because it starts with reassurance:

1. Не волнуйся
2. we’ll make the train
3. if we leave earlier

So the structure matches the speaker’s intention very nicely.

There are two commas for two different reasons.

1. After Не волнуйся

This separates the first clause from the next one:

• Не волнуйся, мы успеем на поезд...

It is like saying:

• Don’t worry, we’ll make the train...

2. Before если

This comma introduces the conditional clause:

• ..., если выйдем пораньше

Russian punctuation strongly marks clause boundaries, so these commas are standard.

Yes, very often that is the most natural English translation.

But grammatically, успеть does not literally mean catch. It means something more like:

• to be in time
• to manage to make it
• to succeed in time

So мы успеем на поезд is literally closer to:

• we’ll be in time for the train
• we’ll make the train

In natural English, though, we’ll catch the train is often a perfectly good translation depending on context.
