После работы я захотел пойти в тихий парк.

Because после requires the genitive case in Russian.

• работа = nominative form
• работы = genitive singular

So:

• после работы = after work

This is a fixed grammar pattern you should learn:

• после урока = after the lesson
• после фильма = after the movie
• после обеда = after lunch

So in this sentence, работы is in the genitive because it follows после.

Захотел means began to want, felt like, or suddenly wanted. It often expresses the moment when the desire appeared.

So:

• я хотел пойти = I wanted to go
• я захотел пойти = I felt like going / I suddenly wanted to go

In this sentence, захотел suggests that after work, the speaker got the desire to go to the park.

This verb is from захотеть, which is perfective. It focuses on the start or arrival of the desire, not just the ongoing state.

In the past tense, Russian verbs agree with the gender of the subject if the subject is singular.

So:

• я захотел = I wanted / felt like it — said by a man
• я захотела = I wanted / felt like it — said by a woman

Russian past tense works this way:

• masculine: -л
• feminine: -ла
• neuter: -ло
• plural: -ли

So the sentence as written sounds like it is spoken by a male speaker.

Both relate to to go, but they are not used the same way.

• идти = imperfective
• пойти = perfective

After захотел, Russian often uses the infinitive that matches the idea of a single, complete action.
Here, пойти means to go off / to head to / to make a trip as one whole event.

So:

• захотел пойти в парк = wanted to go to the park

If you used идти, it would sound more like the process of going rather than the decision to set off there. In many everyday contexts, пойти is the more natural choice after захотел when talking about one intended trip.

Because this sentence expresses motion toward a destination.

With в, Russian uses:

• accusative for motion into / to
• prepositional for location in / inside

Here the speaker wants to go to a quiet park, so the park is the destination. That is why we get:

• в тихий парк = into/to a quiet park

Compare:

• Я пошёл в тихий парк. = I went to a quiet park.
• Я был в тихом парке. = I was in a quiet park.

So:

• тихий парк → accusative masculine inanimate = тихий парк
• в тихом парке would mean in a quiet park, not to a quiet park

It actually is in the accusative, but for masculine inanimate nouns, the accusative often looks exactly like the nominative.

So:

• nominative: тихий парк
• accusative: тихий парк

Because парк is:

• masculine
• singular
• inanimate

the accusative form is the same as the nominative form.

Compare this with an animate masculine noun:

• новый студент = nominative
• вижу нового студента = accusative

So тихий is agreeing correctly with парк; it just happens that the form looks unchanged.

Yes, often it can.

Russian frequently drops subject pronouns when the verb form already makes the subject clear.

So both are possible:

• После работы захотел пойти в тихий парк.
• После работы я захотел пойти в тихий парк.

Including я is still very normal. It can make the sentence a little clearer, more explicit, or slightly more natural depending on context.

Russian uses pronouns less often than English, but not never.

No, Russian word order is relatively flexible, though different orders can change emphasis.

The given sentence is neutral and natural:

• После работы я захотел пойти в тихий парк.

Other possible orders include:

• Я захотел пойти в тихий парк после работы.
• В тихий парк я захотел пойти после работы.

These alternatives may shift emphasis:

• putting после работы first highlights the time setting
• putting в тихий парк first highlights the destination

So the original order is a normal, natural way to present the sentence.

In this context, it means after work in the general everyday sense.

Russian often uses a noun without an article-like distinction, because Russian has no articles such as a or the. So работы can mean:

• after work
• after the work

But in ordinary life, после работы usually means after work as a routine part of the day.

The exact interpretation depends on context, not on an article.

It can suggest either, depending on context.

Literally, в парк with a verb of motion means movement into the park. But in natural English translation, this is often just go to the park.

So:

• пойти в парк = go to the park / go into the park

Russian focuses on the destination with в + accusative. English may choose to or into depending on what sounds most natural in context.

Russian has no articles.

So парк can mean:

• a park
• the park

The listener figures out which one is meant from context.

In this sentence, в тихий парк could mean:

• to a quiet park
• to the quiet park

If no specific park has been mentioned before, English will often translate it as a quiet park. If both speakers already know which park is meant, it could be the quiet park instead.
