Это стало реальностью.

Это means this or it, depending on context.

In Это стало реальностью, it refers to something previously mentioned or understood from the situation. Russian often uses это in places where English might say either this or it.

So the sentence can correspond to:

• This became reality
• It became reality
• This became a reality

The exact English choice depends on context.

Because это is grammatically treated as neuter singular, so the past-tense verb must also be neuter singular.

Past tense in Russian agrees with gender and number:

• стал = masculine
• стала = feminine
• стало = neuter
• стали = plural

Since the subject is это, we use стало.

The dictionary form is стать, which means to become.

Стало is:

• past tense
• neuter singular
• from the perfective verb стать

So:

• стать = to become
• стало = became / has become, for a neuter subject

Because the verb стать usually takes the instrumental case when talking about what something becomes.

So:

• реальность = nominative form, reality
• реальностью = instrumental form, (into/as) reality

This is a very common pattern in Russian:

• стать врачом = to become a doctor
• стать проблемой = to become a problem
• стать реальностью = to become reality

So after стать, the noun describing the new state is usually in the instrumental.

Yes, стать is perfective.

That matters because perfective verbs present the action as a completed event or change:

• становиться = imperfective, to be becoming / to become in a process-oriented sense
• стать = perfective, to become, emphasizing the completed result

So Это стало реальностью means the change happened and the result was reached: it actually became reality.

Yes, but it means something different.

• Это стало реальностью = It became reality / the change was completed
• Это становилось реальностью = It was becoming reality / it was turning into reality, focusing on the process

So the original sentence emphasizes the finished outcome, not the ongoing development.

Russian has no articles like a or the.

So реальностью can mean:

• reality
• a reality
• sometimes even the reality, depending on context

English has to choose an article, but Russian does not mark that directly.

Yes. Russian word order is flexible, though the most neutral version here is:

Это стало реальностью.

Other orders are possible, for example:

• Реальностью это стало.
• Стало это реальностью.

These versions may sound more marked, emphatic, or literary depending on context. For a learner, Это стало реальностью is the safest and most natural default.

Sometimes yes, depending on context, but it is not a word-for-word translation.

Это стало реальностью literally means This became reality or This became a reality.

In natural English, This came true may fit well if the thing was a dream, hope, prediction, or plan. But grammatically, the Russian sentence is built around becoming reality, not the idiom coming true.

It is pronounced approximately:

ree-alʹ-NASTʹ-yu

The stress is on а́ль? Actually in this word the stress is on а́ль? More precisely:

реа́льностью

So the stressed syllable is а́.

A rough breakdown:

• ре = re
• а́ль = stressed ALʹ
• но = no
• стью = stʹyu

The soft sign ь makes the preceding consonant soft.

Yes, it is very natural. It is a common way to say that something once imagined, planned, or hoped for has now become real.

It is often used in contexts like:

• dreams coming true
• scientific advances
• plans finally happening
• ideas turning into facts

So it is both grammatically standard and stylistically natural.
