Я предложил пойти в парк после работы.

Предложил is past tense, and in Russian past tense verbs agree with the subject in gender and number.

Here the subject is я, but Russian past tense still shows the speaker’s gender:

• я предложил = a male speaker
• я предложила = a female speaker
• мы предложили = we suggested

So я предложил tells you the speaker is male.

Russian uses the past tense here because the act of suggesting has already happened. The sentence is about a completed suggestion: I suggested...

The form is built from the infinitive предложить:

• infinitive: предложить
• past masculine singular: предложил

This is very normal after reporting what someone said, suggested, decided, asked, and so on.

After verbs like предложить, Russian often uses an infinitive to say what was suggested.

So:

• предложил пойти = suggested going / suggested that someone go

This works a lot like English:

• I suggested going
• I suggested that we go

In Russian, the infinitive пойти expresses the action that was proposed.

This is a very common question. The difference is aspect and also the specific meaning of the motion verb.

• идти = to be going, to go on foot, process in progress
• пойти = to set off, to go, with focus on the start or single whole action

After предложил, пойти sounds natural because the speaker suggested one complete action/event: going to the park after work.

So:

• предложил пойти в парк = suggested going to the park
• предложил идти в парк would usually sound less natural here unless you are stressing the process or immediate ongoing movement in a specific situation

In everyday Russian, with suggestions like this, пойти is the normal choice.

Historically and grammatically, идти / пойти are the verbs for going on foot. But in many everyday contexts, especially in suggestions about places and activities, Russian speakers use пойти quite naturally even when the exact means of getting there is not the main point.

So пойти в парк usually just means go to the park as an outing or plan. It does not always strongly emphasize walking in the way an English learner might expect.

If the mode of transport really matters, Russian can use other verbs:

• поехать = go by vehicle
• полететь = go by plane
• отправиться = set off, depart

Russian does not explicitly specify that here. The sentence only says that the speaker made a suggestion to go to the park after work.

In real context, it often means something like:

• I suggested that we go to the park after work

But grammatically it could also mean:

• I suggested that he/she/they go
• I suggested going in a more general sense

Russian often leaves this understood from context. If needed, speakers can make it clearer:

• Я предложил нам пойти в парк = I suggested that we go to the park
• Я предложил ему пойти в парк = I suggested that he go to the park

It can, but it does not have to. Russian often omits information that is already clear from context.

So:

• Я предложил пойти в парк после работы. = I suggested going to the park after work.
• Я предложил ему пойти в парк после работы. = I suggested that he go to the park after work.
• Я предложил ей пойти в парк после работы. = I suggested that she go to the park after work.

If the listener already knows who was involved, leaving it out is perfectly natural.

Because Russian uses different cases depending on whether you mean motion toward/into a place or location in a place.

Here there is movement:

• пойти в парк = to go to the park

So парк is in the accusative case:

• в парк

Compare:

• в парке = in the park, at the park, with location and no movement

Examples:

• Мы пошли в парк. = We went to the park.
• Мы были в парке. = We were in the park.

After the preposition после meaning after, Russian uses the genitive case.

So:

• работа = nominative
• после работы = after work

This is a fixed pattern:

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

So работы is genitive singular.

Usually it means the general idea after work. Russian often does not use possessives or articles where English might.

So после работы can naturally mean:

• after work
• after the workday
• after one’s work is over

If needed, Russian can make it more specific:

• после моей работы = after my work
• после работы в офисе = after work at the office

But in ordinary conversation, после работы is the standard way to say after work.

No, Russian word order is fairly flexible. This sentence is in a neutral, natural order, but other orders are possible depending on emphasis.

For example:

• Я предложил пойти в парк после работы. = neutral
• После работы я предложил пойти в парк. = emphasizes after work
• В парк я предложил пойти после работы. = emphasizes to the park
• Пойти в парк после работы я предложил вчера. = emphasizes the whole idea of going

Even though Russian word order can move around, not every order sounds equally neutral. The original version is a very standard one.

Yes, depending on the nuance.

• предложил = suggested / proposed / offered
• посоветовал = advised
• решил = decided
• попросил = asked
• захотел = wanted

For example:

• Я посоветовал пойти в парк после работы. = I advised going to the park after work.
• Я решил пойти в парк после работы. = I decided to go to the park after work.

So предложил specifically gives the idea of making a suggestion or proposal.

Yes. In English, both are often possible depending on style:

• I suggested going to the park after work.
• I suggested that we go to the park after work.

Russian uses the infinitive пойти, but English may express that idea either with going or with a clause like that we go. So the Russian structure does not always map to just one English form.
