Я решил сначала молча выслушать её, а потом попытаться всё уладить.

Решил is the past-tense masculine singular form of решить. Russian past tense agrees with the subject in gender and number.

• Я решил = I decided said by a man
• Я решила = I decided said by a woman

So this sentence is spoken by a male speaker.

After решил, Russian commonly uses an infinitive, just like English uses to + verb.

So:

• Я решил выслушать её = I decided to hear her out
• потом попытаться всё уладить = then to try to settle everything

The structure is:

• решил
  • infinitive
• попытаться
  • infinitive

So the sentence contains a chain:

• decided → to listen
• then → to try
• to settle everything

This kind of stacking of infinitives is very normal in Russian.

This is a very important vocabulary point.

• слушать = to listen
• выслушать = to listen to someone fully, to hear someone out

The prefix вы- adds the sense of carrying the action through to completion. So выслушать её is not just listen to her, but more like:

• hear her out
• listen to everything she has to say

Also, выслушать is perfective, so it presents the action as complete.

Её is the pronoun she/her in the accusative case here, because it is the direct object of выслушать.

• она = she
• её = her

So:

• выслушать её = to hear her out

A useful note: the form её can also be genitive, but in this sentence it is accusative because she is the person being listened to.

These two words organize the sequence of actions.

• сначала = at first, first
• потом = then, afterwards, later

So:

• сначала молча выслушать её = first listen to her silently
• а потом попытаться всё уладить = and then try to settle everything

This is a very common pairing in Russian:

• сначала ..., потом ...
• first ..., then ...

Here а links two stages of the plan:

• first one thing
• then another thing

In this sentence, а потом works like and then or and after that. The conjunction а often introduces a transition, contrast, or change of step.

So:

• сначала ..., а потом ... = first ..., and then ...

Russian often uses а in this kind of two-part structure even when English might simply use then.

Because а is a coordinating conjunction, and it joins two coordinated parts of the sentence:

• сначала молча выслушать её
• а потом попытаться всё уладить

Russian normally puts a comma before а in this kind of structure.

So the comma is standard punctuation here.

Молча means silently, without speaking.

That is slightly different from тихо, which usually means quietly. A person can do something тихо and still speak a little; молча specifically means not saying anything.

So:

• молча выслушать её = to listen to her in silence
• тихо выслушать её would sound less natural here and would focus more on quietness than on not speaking

Молча is the natural word when the idea is: listen without interrupting or responding.

Because it modifies the way the action is done: listen silently.

Russian word order is flexible, but placing молча before the verb is very natural here:

• сначала молча выслушать её

It keeps the sentence flowing smoothly and emphasizes the manner of listening before the action itself.

You could also encounter other word orders in Russian, but this one is very standard and natural.

Попытаться means to try, to attempt.

So:

• попытаться всё уладить = to try to settle everything

If the sentence said just потом всё уладить, it would sound more definite: the speaker decided to settle everything. But попытаться shows less certainty and more realism: the speaker intends to make an effort, but success is not guaranteed.

So it adds the meaning of attempt.

Here всё means everything or it all.

In context, it usually refers to the whole situation, conflict, or problem between the people involved.

So всё уладить means:

• settle everything
• sort it all out
• smooth the whole situation over

It does not necessarily mean literally every single thing in the world; it means everything relevant to the situation.

Уладить means to settle, to straighten out, to smooth over, to resolve a difficult situation.

It is often used for:

• arguments
• problems
• misunderstandings
• awkward situations

So всё уладить suggests restoring peace or fixing the problem diplomatically.

Also, уладить is perfective, so it presents the action as a completed resolution.

Both verbs present the actions as whole, completed actions in the speaker’s plan.

• выслушать = hear her out completely
• уладить = settle the situation completely

This makes sense after решил, because the speaker is describing a plan with clear, bounded steps:

1. listen to her fully
2. try to resolve everything

If imperfective forms were used, the meaning would shift toward process or repeated action, and it would sound less natural in this context.

Yes, Russian word order is flexible, but the original order is natural and clear.

For example, you could say:

• Я решил её сначала молча выслушать, а потом попытаться всё уладить.

This is also understandable, but the original:

• Я решил сначала молча выслушать её, а потом попытаться всё уладить.

sounds smooth and keeps the focus on the sequence of actions.

So yes, some variation is possible, but the given version is a very natural standard phrasing.
