Этот район города тихий и зелёный.

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

So:

• Этот район города тихий и зелёный. literally = This district of the city quiet and green.

But in natural English, we translate it as This district of the city is quiet and green.

Russian does use forms of to be in the past and future, but not usually in the present in sentences like this.

Because города is in the genitive case.

The phrase район города means:

• район = district / area
• города = of the city

So the structure is:

• район чего? = district of what?
• города = of the city

This is a very common Russian pattern:

• центр города = the city center / center of the city
• улицы города = the streets of the city
• жители города = the residents of the city

Этот means this, and it agrees with район.

Since район is:

• masculine
• singular
• nominative

the correct form is этот.

Compare:

• этот район = this district
• эта улица = this street
• это здание = this building
• эти дома = these houses

So этот is chosen because район is a masculine singular noun.

Both are normal masculine singular nominative adjective endings.

In this sentence, both adjectives describe район, so they must match it:

• район = masculine, singular, nominative
• therefore: тихий and зелёный

The reason one ends in -ий and the other in -ый is mostly due to the adjective’s dictionary form and spelling pattern, not because they are doing different grammatical jobs.

So here:

• тихий район = a quiet district
• зелёный район = a green district

Both adjectives agree correctly with район.

Not necessarily just the color.

In a sentence like this, зелёный often means green in the sense of:

• full of trees
• full of plants
• leafy
• having a lot of green space

So тихий и зелёный район suggests a place that is:

• peaceful
• pleasant
• with parks, trees, or greenery

This is very natural in both Russian and English.

The correct spelling is зелёный, with ё.

The letter ё shows that the word is pronounced with yo:

• зе-лё-ный

However, in many Russian texts, especially informal or printed ones, ё is often replaced by е, so you may also see зеленый.

Important point:

• зелёный and зеленый are the same word
• the pronunciation is still зелёный

For learners, it is helpful to remember the ё, because it makes pronunciation clearer.

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

The neutral, natural order here is:

• Этот район города тихий и зелёный.

This presents the topic first (this district of the city) and then says something about it (is quiet and green).

You might also hear variations for emphasis, but this version is the most straightforward for a learner.

In ordinary description, this is the best order to use.

Yes. Район can mean several related things depending on context, such as:

• district
• area
• neighborhood
• part of a city

So Этот район города could be translated in different ways depending on the situation:

• This district of the city
• This part of the city
• This neighborhood in the city

All are possible. The exact English choice depends on what meaning has already been given in context.

Russian adjectives have long forms and short forms.

Here, the long forms are used:

• тихий
• зелёный

That is normal when you are simply describing a noun in a neutral way.

Short forms also exist, for example:

• тих
• зелён

But short forms are used differently and can sound more literary, formal, or stylistically marked, especially with some adjectives.

For everyday descriptive sentences, the long forms in this sentence are the most natural choice.

Район is in the nominative singular.

It is the subject of the sentence:

• Этот район города = this district of the city

Since тихий и зелёный describe that subject, they are also in the nominative singular masculine form.

So the basic structure is:

• subject: Этот район города
• description/predicate: тихий и зелёный

A very literal breakdown would be:

• Этот = this
• район = district / area
• города = of the city
• тихий = quiet
• и = and
• зелёный = green

So word-for-word:

• This district of the city quiet and green

Natural English adds is:

• This district of the city is quiet and green.

This is a good example of how Russian often leaves out the present-tense to be, even though English requires it.
