Мне становится всё легче говорить по-русски.

Because this sentence uses an impersonal construction.

Russian often expresses feelings, states, and changing conditions with:

• dative experiencer
  • state/change

So мне literally means to me / for me, and the idea is:

• Мне становится легче = It is becoming easier for me

English usually says I am finding it easier or It is getting easier for me, but Russian does not need я here.

Because Russian does not need a dummy subject the way English does.

In English, we often say:

• It is getting easier

But that it does not really refer to anything. Russian usually just leaves that kind of subject out:

• Мне становится легче

So the sentence is perfectly complete without это.

Становится is from становиться, which means to become or to get.

Here it means:

• is becoming
• is getting

So:

• Мне становится всё легче... = It is becoming easier and easier for me...

Grammatically, становится is:

• 3rd person singular
• present tense
• imperfective

In this sentence, it is used impersonally.

Because the dictionary form of this verb is становиться.

The -ся here is just part of the verb. It does not mean a literal reflexive idea like becomes itself.

This is very common in Russian: many verbs with -ся do not translate as reflexives in English.

Compare:

• становить = to set, place, position
• становиться = to become

So for this meaning, you need становиться, not становить.

Here всё means more and more, increasingly, or ever.

With comparatives, Russian often uses:

• всё лучше = better and better
• всё труднее = harder and harder
• всё легче = easier and easier

So in this sentence:

• всё легче = easier and easier

Also, this is всё, not все.

• всё = everything / more and more in this pattern
• все = all people / all things in the plural

Легче is the comparative form of легко and лёгкий.

In this sentence, it means:

• easier

Russian often uses this comparative form in impersonal patterns like:

• Мне легче читать. = It is easier for me to read.
• Ей труднее понять. = It is harder for her to understand.

Here легче is not describing a noun, so it does not change for gender or number. That is why you do not see forms like лёгкий, лёгкая, or лёгкое.

In practical terms, it behaves like a predicative comparative.

For a learner, the simplest way to think about it is:

• it means easier
• it is used as the main word describing the situation
• it does not agree with a noun

It is closely related to both:

• лёгкий = easy, light
• легко = easily, easy

But in this sentence, it functions as the kind of word Russian commonly uses in patterns like:

• мне трудно
• ей легко
• нам легче

So you can treat легче here as the comparative form used in a state expression.

Because Russian uses the infinitive after words like легко, трудно, легче, лучше, and similar expressions when talking about an action in general.

So:

• говорить по-русски = to speak Russian

The whole idea is:

• It is becoming easier for me to speak Russian

Compare:

• Мне трудно понять. = It is hard for me to understand.
• Ему легче работать утром. = It is easier for him to work in the morning.

Using a finite verb such as говорю would not fit this structure.

По-русски means in Russian or in the Russian language.

After verbs of speaking, this is a very common pattern:

• говорить по-русски = to speak Russian
• говорить по-английски = to speak English
• говорить по-французски = to speak French

So по-русски is an adverb, not an adjective.

It tells you how / in what language someone is speaking.

They are similar, but not always identical in feel or usage.

Very roughly:

• по-русски is especially common with speaking
• на русском often means in Russian as the language of something

Examples:

• Я говорю по-русски. = I speak Russian.
• Книга написана на русском. = The book is written in Russian.

With говорить, по-русски is the most standard and natural choice.

Yes, you can, but the meaning changes slightly.

• Мне всё легче говорить по-русски. = It is easier and easier for me to speak Russian.
• Мне становится всё легче говорить по-русски. = It is becoming easier and easier for me to speak Russian.

The version with становится makes the idea of change over time more explicit.

Without становится, the sentence is still natural, but it is a bit more compressed.

It is in the present tense.

• становится = present tense of становиться

But the meaning is dynamic: it describes a process happening now, so in English it often translates as:

• is getting easier
• is becoming easier

If you wanted a future meaning, you could say:

• Мне станет легче говорить по-русски. = It will become easier for me to speak Russian.

Quite literal in meaning, but not in grammar.

A very literal unpacking would be something like:

• To me it becomes ever easier to speak in Russian

Natural English would usually be:

• It’s getting easier and easier for me to speak Russian.

So the main differences are:

• Russian uses мне instead of I
• Russian omits the dummy subject it
• Russian uses всё + comparative for more and more
• Russian uses the infinitive говорить for the action

Yes. Russian word order is flexible, and changes mainly affect emphasis, not the core meaning.

The neutral order is:

• Мне становится всё легче говорить по-русски.

Possible variations include:

• Говорить по-русски мне становится всё легче.
• Всё легче мне становится говорить по-русски.

These still mean roughly the same thing, but they highlight different parts of the sentence.

For a learner, the original order is a very good standard model to use.
