Это неправда.

In Russian, the verb to be is usually omitted in the present tense.

So where English says:

• This is not true
• That is not true

Russian simply says:

• Это неправда

A full present-tense есть would sound unnatural here. Russian normally does not use it in sentences like this.

Это usually means this, that, or sometimes it, depending on context.

In Это неправда, it points to some statement, idea, or situation and means something like:

• this
• that
• it

So это is referring to whatever was just said or mentioned.

Неправда is a noun, not an adjective.

It literally means something like:

• untruth
• not true
• falsehood

In this sentence, Russian uses a noun where English often uses an adjective phrase. So instead of saying literally This is not-true, Russian says something closer to This is untrue / This is an untruth.

Grammatically, неправда is:

• feminine
• singular
• nominative case

Because неправда is commonly treated as a single word with its own meaning: untruth, not true, falsehood.

So:

• неправда = a normal dictionary word

You may also see не правда written separately, but that usually happens when the speaker is making a stronger contrast or denial, for example:

• Это не правда, а ложь. = This is not truth, but a lie.

In the simple sentence Это неправда, writing it as one word is the normal choice.

Yes. It is a very common, natural, neutral sentence.

You can use it in everyday conversation when reacting to something false or incorrect.

It is not especially formal or especially slangy. It works in most normal situations.

Yes, but the meaning is a bit stronger.

• Это неправда = That’s not true / That’s false
• Это ложь = That’s a lie

The second version often suggests that someone is being deliberately dishonest, not just mistaken. So Это ложь can sound harsher or more accusatory.

The ending -а is a common ending for feminine nouns in Russian.

So правда is a feminine noun, and неправда keeps the same grammatical pattern.

That is why, if you later see adjectives agreeing with it, they would normally be feminine too, for example:

• Это полная неправда. = That is complete nonsense / complete untruth.

Here полная is feminine because неправда is feminine.

The stress is:

• Э́то непра́вда

A rough pronunciation guide:

• EH-ta ni-PRAV-da

A few notes:

• Это has stress on the first syllable: Э́то
• неправда has stress on пра́в

In natural speech, unstressed vowels are reduced, so it may sound a bit more like ni-PRAV-da than a fully clear ne-prav-da.

Yes, but Это неправда is the normal, neutral order.

Russian word order is more flexible than English, so other orders are possible for emphasis, but they sound less neutral. For example:

• Это неправда. = normal
• Неправда это. = more marked, emotional, or stylistically unusual

For learners, Это неправда is the safest and most natural form to use.

It can correspond to either this or that in English, depending on context.

Russian это is often less strict than English about distance. In many cases, English chooses between this and that, but Russian simply uses это.

So Это неправда could be translated as:

• This is not true
• That is not true
• It’s not true

The surrounding context tells you which English version fits best.
