По вечерам я люблю перечитывать этот роман.

По вечерам is a very common Russian way to express a habitual/repeated time: in the evenings, every evening, on evenings in general.

• по вечерам = in the evenings / evenings
• вечером = in the evening / this evening / during the evening

So in this sentence, по вечерам emphasizes that this is something the speaker likes to do regularly, not just once.

Вечерам is dative plural.

The preposition по often takes the dative, and one of its common uses is to describe something happening at repeated times:

• по утрам = in the mornings
• по вечерам = in the evenings
• по выходным = on weekends

So this is a fixed, very useful pattern: по + dative plural for repeated time expressions.

Because перечитывать means to reread, not just to read.

Compare:

• читать = to read
• перечитывать = to reread, to read again

The prefix пере- here adds the idea of again. So the sentence is specifically about reading the same novel again and again.

This is about aspect.

• перечитывать = imperfective
• перечитать = perfective

After люблю when talking about something you generally enjoy doing, Russian normally uses the imperfective infinitive:

• Я люблю читать. = I like reading.
• Я люблю гулять. = I like walking.
• Я люблю перечитывать этот роман. = I like rereading this novel.

Why? Because the speaker is describing a habit, process, or general preference, not one completed action.

Using перечитать here would sound much less natural, because the perfective focuses on a completed result.

The difference is in what exactly the speaker enjoys:

• люблю читать = I like reading
• люблю перечитывать = I like rereading

So люблю читать этот роман would mean something like I like reading this novel, while люблю перечитывать этот роман means the speaker already knows the book and enjoys coming back to it again.

Роман is in the accusative case, because it is the direct object of перечитывать.

However, роман is a masculine inanimate noun, and for masculine inanimate nouns, the accusative looks the same as the nominative.

So:

• nominative: этот роман
• accusative: этот роман

That is why the form does not change.

Russian has no articles like a or the.

The word этот means this and points to a specific novel. It is a demonstrative, not an article.

So:

• этот роман = this novel
• роман by itself = could mean a novel, the novel, or just novel, depending on context

In this sentence, этот tells us the speaker means one particular novel.

Yes, sometimes.

Russian often leaves out subject pronouns when the verb already makes the subject clear:

• Люблю перечитывать этот роман.

Because люблю already means I love / I like, я is not always necessary.

But including я is also perfectly normal. It can make the sentence feel a bit clearer, more balanced, or slightly more emphatic.

So both are possible:

• Я люблю перечитывать этот роман.
• Люблю перечитывать этот роман.

Russian word order is flexible, and the beginning of the sentence often contains what the speaker wants to set up first, such as time, place, or topic.

So:

• По вечерам я люблю перечитывать этот роман.

puts the time frame first: In the evenings...

You could also say:

• Я люблю по вечерам перечитывать этот роман.
• Этот роман я люблю перечитывать по вечерам.

These versions are all grammatical, but the emphasis shifts slightly.

The original sentence is very natural because it starts with the time expression and then tells us what the speaker likes to do at that time.

They are close, but not always identical in tone.

• по вечерам = in the evenings / evenings / as a regular evening habit
• каждый вечер = every evening

Каждый вечер sounds a bit more explicit and literal.
По вечерам often sounds smoother and more idiomatic when talking about routine.

Compare:

• По вечерам я читаю. = I read in the evenings.
• Каждый вечер я читаю. = I read every evening.

Both are correct, but по вечерам often feels more like a general pattern.

The stresses are:

По вечера́м я люблю́ перечи́тывать э́тот рома́н.

Word by word:

• по вечера́м
• я
• люблю́
• перечи́тывать
• э́тот
• рома́н

This is useful because Russian stress is unpredictable and can change from form to form. For example:

• ве́чер but вечера́м

So it is worth learning the stressed form together with the word.

Not necessarily.

In sentences like this, люблю often corresponds more naturally to like in English:

• Я люблю читать. = I like reading.
• Я люблю перечитывать этот роман. = I like rereading this novel.

Russian любить covers both stronger and milder meanings depending on context. So even though the verb literally relates to love, the most natural English translation here is often like.
