Мы идём медленно по извилистой тропинке в парке.

Because идти and ходить are both translated as to go / to walk, but they are used differently.

• идти = going in one direction, right now or for one specific trip
• ходить = going habitually, repeatedly, or in different directions

So Мы идём медленно... means we are walking / going slowly at this moment, along a particular path.

Compare:

• Мы идём в парк. = We are going to the park now.
• Мы ходим в парк каждую неделю. = We go to the park every week.

In this sentence, the speaker is describing an action in progress, so идём is the natural choice.

Идём is the 1st person plural present-tense form of идти.

That means:

• мы = we
• идём = we go / we are going

A short pattern:

• я иду = I am going
• ты идёшь = you are going
• он / она идёт = he / she is going
• мы идём = we are going
• вы идёте = you are going
• они идут = they are going

So Мы идём is simply we are going / we are walking.

Yes, it is important.

Ё shows both the pronunciation and the stress:

• идём is pronounced roughly ee-DYOM
• the stress is on the final syllable

In many Russian texts, ё is often written as е, so you may also see идем, but it still means идём. For learners, it is very helpful to remember the ё because it makes pronunciation clearer.

Yes, it could be omitted.

Russian often leaves out subject pronouns when the verb form already makes the subject clear. Since идём already means we are going, the sentence could also be:

• Идём медленно по извилистой тропинке в парке.

That still means We are walking slowly along the winding path in the park.

However, мы may be included:

• for emphasis
• for clarity
• because the speaker wants to make the subject explicit

So both are possible, but мы is not always necessary.

Медленно means slowly, so it describes how the action is done. That makes it an adverb.

It modifies the verb идём:

• Мы идём медленно = We are walking slowly

Russian word order is fairly flexible, so медленно can move around:

• Мы медленно идём по извилистой тропинке в парке.
• Мы идём по извилистой тропинке медленно.

These are all grammatical, but the original order sounds natural and neutral.

It is dative case.

The preposition по often means along, on, or according to, and when it has the meaning along / over / through by way of, it commonly takes the dative.

So:

• по тропинке = along the path

The noun тропинка is feminine singular. In the dative singular, it becomes:

• тропинка → тропинке

So the sentence uses по + dative to express movement along the path.

Because adjectives in Russian must agree with the noun they describe in:

• gender
• number
• case

Here, the noun is:

• тропинке = dative singular feminine

So the adjective извилистая must also be in the dative singular feminine form:

• nominative: извилистая тропинка
• dative: извилистой тропинке

That is why the ending changes to -ой.

Извилистый means winding, twisting, or curving.

So извилистая тропинка is a winding path.

It is a normal descriptive word, especially for roads, paths, rivers, and routes. For example:

• извилистая дорога = a winding road
• извилистая река = a winding river

In your sentence, it paints a vivid picture of the path not being straight.

Because в парке expresses location: in the park.

The preposition в can take different cases depending on meaning:

• в + accusative = motion into something
• в + prepositional = location inside something

Here, the meaning is location, not motion into the park. The action is happening there.

So:

• парк = park
• в парке = in the park

This is the prepositional singular form.

Compare:

• Мы идём в парк. = We are going into / to the park.
• Мы идём в парке. = We are walking in the park.

Парке is the prepositional singular of парк.

For many masculine nouns ending in a consonant, the prepositional singular is formed with -е:

• парк → в парке
• дом → в доме
• город → в городе

So в парке is simply the location form after в when the meaning is in the park.

Russian does not have articles.

So a noun like тропинка can mean:

• a path
• the path

The exact meaning depends on context.

In this sentence, English naturally uses the winding path or a winding path, depending on the situation, but Russian does not mark that difference with a separate word.

Russian instead relies on:

• context
• word order
• emphasis
• sometimes demonstratives like этот = this

Yes.

Идём is present tense, and with a verb like идти, it usually describes an action happening now or around now.

So the sentence most naturally means that the speakers are currently walking slowly along the path.

Russian present tense often covers what English expresses with both:

• we go
• we are going

But with идти in this kind of context, English usually prefers we are walking / we are going.

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

The original sentence:

• Мы идём медленно по извилистой тропинке в парке.

is neutral and natural.

But other orders are possible, for example:

• Мы медленно идём по извилистой тропинке в парке.
• По извилистой тропинке в парке мы идём медленно.

These versions may shift emphasis slightly:

• putting медленно earlier emphasizes the slow pace
• putting по извилистой тропинке в парке first emphasizes the setting or route

So the grammar still works, but the focus changes.

Тропинка is a diminutive form of тропа.

Very roughly:

• тропа = path, trail
• тропинка = little path, small path, footpath

In modern Russian, diminutives do not always sound strongly emotional. Sometimes they simply sound more natural for small, narrow, or informal things.

So тропинка often suggests:

• a narrow path
• a more picturesque or natural path
• something smaller than a road or broad trail

That fits very well with a sentence about walking in a park.

Because Russian and English use different prepositions to express route and movement.

In this sentence, по means something like:

• along
• by way of
• over the course of

So по извилистой тропинке is naturally translated as along the winding path.

You should not expect one Russian preposition to match one English preposition exactly every time. It is better to learn common patterns such as:

• идти по дороге = walk along the road
• гулять по парку = walk around the park
• читать по книге is not the same pattern and means something else entirely

So with movement along a surface or route, по + dative is a very useful pattern to remember.
