Вечером мы гуляли в тихом сквере.

Вечером is the instrumental singular form of вечер. In Russian, some time expressions are commonly put in the instrumental case without a preposition to mean at a certain time or during a certain part of the day.

So:

• утром = in the morning
• днём = in the daytime / in the afternoon
• вечером = in the evening
• ночью = at night

This is why Russian does not need a word like in before вечером.

Гуляли is the past tense plural form of гулять, which often means to walk, to stroll, or to spend time walking around.

Why this form?

• гулять is imperfective
• гуляли = we were walking / we walked / we used to walk, depending on context

In this sentence, it describes the activity as a process or general event in the past, not as a completed one-time result.

Compare:

• мы гуляли = we were walking / we walked
• мы погуляли = we had a walk / we went for a walk and finished it

A learner often wonders why not погуляли. You could say Вечером мы погуляли в тихом сквере, but that sounds more like we went for a walk in the quiet square/park and that action was completed. The original sentence is more neutral and descriptive.

This is the standard past tense plural ending in Russian.

The infinitive is гулять.
To form the past tense, Russian usually uses the stem plus past endings:

• masculine singular: гулял
• feminine singular: гуляла
• neuter singular: гуляло
• plural: гуляли

Because the subject is мы = we, the verb must be plural, so we get гуляли.

Because here в means in, showing location, not movement toward a destination.

Russian uses different cases after в:

• в + accusative = motion into / to
  
  • в тихий сквер = into the quiet square/park
• в + prepositional = location in / inside
  
  • в тихом сквере = in the quiet square/park

In this sentence, the people were already walking in that place, so Russian uses the prepositional case:

• в тихом сквере

Because both words are in the prepositional case, singular, masculine.

The noun is:

• сквер = square / small park / public garden

After в meaning in a place, it becomes:

• в сквере

The adjective must agree with the noun in gender, number, and case:

• nominative masculine singular: тихий сквер
• prepositional masculine singular: в тихом сквере

So:

• тихий → тихом
• сквер → сквере

Not exactly.

Сквер usually means a small public garden, small park, or landscaped square, often in a town or city. It is usually smaller than a парк.

Rough comparison:

• парк = park
• сквер = small park / square with trees and paths
• сад = garden

So в тихом сквере gives a slightly more specific image than just in a park.

Yes, Russian can often omit subject pronouns when the verb form already makes the subject clear.

So both are possible:

• Вечером мы гуляли в тихом сквере.
• Вечером гуляли в тихом сквере.

The first version with мы is perfectly normal and may sound a bit clearer or slightly more explicit. Russian often includes pronouns for emphasis, contrast, clarity, or just style.

Yes. Russian word order is more flexible than English word order because the grammatical endings show the relationships between words.

This sentence can be rearranged in different ways, for example:

• Вечером мы гуляли в тихом сквере.
• Мы вечером гуляли в тихом сквере.
• В тихом сквере мы гуляли вечером.

These versions are all understandable, but the emphasis changes.

The original order sounds natural and neutral:

• Вечером sets the time first
• мы гуляли gives the action
• в тихом сквере gives the place

Russian has no articles like a or the. The listener understands that from context.

So в тихом сквере could mean:

• in a quiet square/park
• in the quiet square/park

The exact choice in English depends on the wider context, not on a separate Russian word.

The main stresses are:

• ве́чером
• мы
• гуля́ли
• в
• ти́хом
• скве́ре

A rough pronunciation guide:

• ве́чером = VYE-che-ram
• гуля́ли = goo-LYA-li
• ти́хом = TEE-kham
• скве́ре = SKVYE-re

For learners, гуля́ли and скве́ре are especially worth practicing because the stressed syllable affects vowel quality.

Sometimes, yes — but context matters.

A bare form like вечером can mean:

• that evening / in the evening in a specific situation
• sometimes in the evenings in a habitual context

For example:

• Вечером мы гуляли в тихом сквере.
  Most naturally: In the evening, we walked in a quiet square/park or That evening, we were walking...

But in a habitual context:

• Летом вечером мы гуляли в сквере.
  This could mean In the summer, we used to walk in the square in the evenings.

So the form itself does not force only one interpretation; the broader context decides.
