После ужина мы любим гулять по тихой улице.

Because the preposition после always requires the genitive case.

• ужин = nominative, dinner
• после ужина = after dinner

So this is a very common pattern:

• после работы = after work
• после урока = after the lesson/class
• после фильма = after the film

That is why you see ужина, not ужин.

Because after любить when you mean to like doing something, Russian normally uses the infinitive.

So:

• любим гулять = we like to walk
• literally: we love/like to walk

You do the same with many verbs in Russian:

• Я люблю читать. = I like reading / I like to read.
• Она любит петь. = She likes singing / She likes to sing.

A finite verb like гуляем would not fit here after любим.

It is the dative case.

The preposition по often takes the dative when it means something like:

• along
• around
• through
• over a surface or area, depending on context

So:

• по улице = along the street / around the street area
• по тихой улице = along the quiet street

Here the forms are:

• улица → улице (dative singular)
• тихая → тихой (dative singular feminine)

So гулять по тихой улице means to walk along a quiet street.

Because adjectives must agree with the noun they describe in gender, number, and case.

The noun is:

• улица = feminine singular

But after по, it becomes dative singular:

• улица → улице

So the adjective must also become dative singular feminine:

• тихая → тихой

That gives:

• по тихой улице

This agreement is one of the most important features of Russian grammar.

In this sentence, любим is usually best translated as like or love, depending on tone.

• мы любим гулять = we like walking / we like to walk
• It can also sound a bit stronger: we love walking

Russian любить often covers both ideas. In everyday translation, English usually chooses the more natural option based on context.

So in this sentence, любим does not necessarily sound overly emotional. It is a normal way to say that someone enjoys doing something regularly.

Because the sentence describes a general habit or preference, not one completed action.

Гулять is the imperfective verb, and it is used for:

• habitual actions
• repeated actions
• general activities
• ongoing processes

Here, мы любим гулять means we like to go walking / we like walking in general.

A perfective verb would not fit well here, because perfective verbs usually focus on a single completed result, and that is not the point of this sentence.

Because Russian has no articles like a/an or the.

So Russian simply says:

• после ужина
• по тихой улице

Whether English translates this as after dinner, after the dinner, along a quiet street, or along the quiet street depends on context.

Russian leaves that information unstated unless something else makes it clear.

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

The neutral order here is:

• После ужина мы любим гулять по тихой улице.

But other orders are possible, for example:

• Мы любим гулять по тихой улице после ужина.
• По тихой улице мы любим гулять после ужина.

These versions are still grammatical, but the emphasis changes slightly.

The original sentence sounds natural and neutral, with После ужина setting the time at the beginning.

Here it most naturally means along the quiet street or down the quiet street.

That is because гулять по улице is a common Russian expression for walking around or along a street.

Compare:

• гулять по улице = walk along/down the street
• быть на улице = be outside / be on the street

So по тихой улице emphasizes movement through or along that street, not just location.

It most naturally expresses a general habit or usual preference.

• Мы любим гулять после ужина. = We like walking after dinner.

It suggests something the speakers generally enjoy doing, not just what they are doing once.

That habitual meaning comes from:

• любим = we like/love
• гулять imperfective = general activity

So the sentence sounds like a routine or a common preference.

The main stresses are:

• После — ПОсле
• ужина — Ужина
• любим — ЛЮбим
• гулять — гуля́ть
• тихой — ТИхой
• улице — Улице

A rough pronunciation guide:

• ПО-сле У-жина мы ЛЮ-бим гу-ЛЯТЬ по ТИ-хой У-лице

For learners, гулять is often the trickiest word because of the soft consonants and the stressed final -ять sound.
