Это хорошая сделка.

Because это here is not directly describing the noun сделка. It is a separate word meaning this or it/this is.

So the sentence structure is:

• Это = this / this is / it is
• хорошая сделка = a good deal

If you wanted this deal as one noun phrase, then you would say:

• эта сделка = this deal

Compare:

• Это хорошая сделка. = This is a good deal.
• Эта сделка хорошая. = This deal is good.

That difference is very common and important.

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

So:

• Это хорошая сделка. literally looks like This good deal
• but it means This is a good deal

This is normal Russian grammar.

Compare:

• Он врач. = He is a doctor.
• Она дома. = She is at home.

In the past or future, forms of to be do appear:

• Это была хорошая сделка. = This was a good deal.
• Это будет хорошая сделка. = This will be a good deal.

Because хорошая agrees with сделка, which is:

• feminine
• singular
• nominative case

Russian adjectives change their endings to match the noun they describe.

Here are some forms of good:

• хороший = masculine
• хорошая = feminine
• хорошее = neuter
• хорошие = plural

Examples:

• хороший стол = a good table
• хорошая сделка = a good deal
• хорошее место = a good place
• хорошие книги = good books

A very common clue is the ending. Nouns ending in -а or -я are often feminine.

So:

• сделка ends in -а
• therefore it is feminine

That is why the adjective must also be feminine:

• хорошая сделка

There are exceptions in Russian, but for a beginner this is a very useful rule.

It is in the nominative case.

This sentence is an identification/equation sentence:

• Это = subject-like element
• хорошая сделка = what it is identified as

In simple present-tense sentences like this, the noun is usually nominative:

• Это проблема. = This is a problem.
• Это хорошая идея. = This is a good idea.
• Это хорошая сделка. = This is a good deal.

Сделка usually means deal, transaction, or agreement, especially in a business, financial, or negotiating context.

So Это хорошая сделка often means:

• This is a good deal
• This is a good bargain
• This is a good transaction

Depending on context, English may translate it slightly differently.

For example:

• in shopping, it may feel like a bargain
• in business, it may feel more like a deal or transaction

Russian does not have articles like a, an, and the.

So:

• хорошая сделка can mean a good deal or the good deal
• context tells you which one sounds natural in English

In this sentence, English normally uses a:

• This is a good deal.

This is one of the biggest differences between English and Russian.

Yes. Russian word order is more flexible than English word order.

The most neutral version is:

• Это хорошая сделка.

But other orders are possible, depending on emphasis:

• Хорошая это сделка.
• Сделка хорошая.
• Это сделка хорошая.

These do not all sound equally neutral. A learner should usually stick with:

• Это хорошая сделка.

It is the most straightforward and natural basic sentence.

A good pronunciation guide is:

• Э́то хоро́шая сде́лка.

Approximate English-style pronunciation:

• EH-tuh kha-RO-sha-ya ZDYEL-ka

A few notes:

• х sounds like the ch in Scottish loch or German Bach
• сд in сделка is a consonant cluster; many learners hear something like zdyelka
• the stress is on:
  • Э́ in это
  • ро́ in хоро́шая
  • де́ in сде́лка

Yes, very often.

In sentences like this, это can be translated naturally as:

• this
• it
• sometimes that, depending on context

So all of these could fit in the right situation:

• This is a good deal.
• It’s a good deal.

Russian uses это very broadly in this kind of structure.

You could, but it sounds less neutral and more marked.

Russian word order can shift to highlight information. When you say:

• Это хорошая сделка.

you are simply stating the idea in a normal way.

If you say:

• Это сделка хорошая.

it may sound like you are contrasting this deal with another one, as if implying:

• This deal is the good one
• or This deal, at least, is good

So for basic learning, use:

• Это хорошая сделка.

They are close, but not identical.

• Это хорошая сделка. = This is a good deal.
• Эта сделка хорошая. = This deal is good.

The first sentence introduces or identifies something. The second talks about a specific deal and comments on it.

So:

• это = this is
• эта сделка = this deal

That distinction is one of the most useful things to notice in this sentence.
