Я люблю повторять новые слова утром.

Because in Russian, after verbs like любить when you mean to like/love doing something, you normally use an infinitive.

So:

• Я люблю повторять... = I like/love to review/repeat...
• literally: I love to repeat...

This is very similar to English I like reading, I like to read.

Other examples:

• Я люблю читать. = I like reading.
• Я люблю готовить. = I like cooking.

This is about verb aspect.

• повторять = imperfective
• повторить = perfective

The imperfective is used here because the sentence talks about a habit, general preference, or repeated activity: reviewing words in general, not one single completed act.

So:

• Я люблю повторять новые слова утром. = I like reviewing new words in the morning.
  This sounds natural for a routine or general preference.

If you said люблю повторить, it would usually sound unnatural here, because perfective verbs focus on a completed result, and любить + perfective is much less common in this kind of general statement.

Here повторять means something like:

• to repeat
• to review
• to go over again

In language-learning contexts, повторять слова often means to review vocabulary.

So although the literal meaning is repeat, a natural English translation might be:

• I like reviewing new words in the morning.

Новые слова is in the accusative case, because it is the direct object of повторять.

You are repeating what?
→ новые слова

For inanimate plural nouns, the accusative is the same as the nominative.

So:

• nominative: новые слова
• accusative: новые слова

That is why the form does not change here.

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

• gender
• number
• case

The noun слова is:

• plural
• accusative
• inanimate

So the adjective must also be plural accusative inanimate:

• новые слова = new words

Compare:

• новое слово = a new word
• новые слова = new words

Yes. The singular form is:

• слово = word

The plural is:

• слова = words

This is a normal neuter noun pattern in Russian:

• окно → окна
• письмо → письма
• слово → слова

So новые слова simply means new words.

Because утром is a special adverbial use of the instrumental case meaning in the morning.

So:

• утро = morning
• утром = in the morning

This is very common with parts of the day:

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

So утром is the correct form when talking about when something happens.

Good question. Both can often be translated as in the morning, but there is a nuance:

• утром = in the morning / this happens in the morning
• по утрам = in the mornings / regularly every morning or on mornings in general

So:

• Я люблю повторять новые слова утром.
  = I like reviewing new words in the morning.

• Я люблю повторять новые слова по утрам.
  = I like reviewing new words in the mornings.

The second version sounds a bit more clearly habitual.

Yes. Russian word order is more flexible than English because case endings show grammatical roles.

The neutral order here is:

• Я люблю повторять новые слова утром.

But you could also say:

• Утром я люблю повторять новые слова.
• Новые слова я люблю повторять утром.

These versions shift the focus or emphasis:

• Утром... emphasizes the time.
• Новые слова... emphasizes what you like to review.

Even though the word order changes, the basic meaning stays similar.

Yes, often you can, because the verb ending already shows the subject.

• люблю clearly means I love / I like

So in context, you can say:

• Люблю повторять новые слова утром.

This is natural in conversational Russian.

However, Я is often included:

• for clarity
• for emphasis
• at the start of a sentence
• when contrasting with someone else

For example:

• Я люблю повторять слова утром, а он вечером.
  = I like reviewing words in the morning, but he does it in the evening.

Not always. In Russian, люблю can mean either:

• I love
• I like

depending on context.

With activities, it often sounds like I like or I really enjoy:

• Я люблю читать. = I like reading / I love reading.
• Я люблю гулять. = I like walking.

So in this sentence, люблю does not necessarily mean intense emotion. It can simply mean that the speaker enjoys this activity.

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

So новые слова could mean:

• new words
• the new words

The exact meaning depends on context.

This is something English speakers often notice right away: Russian simply does not mark definiteness with articles.

Yes, but the meaning changes.

• учить новые слова = to learn/study/memorize new words
• повторять новые слова = to review/repeat new words

So:

• Я люблю учить новые слова утром.
  = I like learning new words in the morning.

• Я люблю повторять новые слова утром.
  = I like reviewing new words in the morning.

Both are correct, but they describe different actions.

A helpful stress guide is:

• Я люблю́ повторя́ть но́вые слова́ у́тром.

Main stressed syllables:

• люблю́
• повторя́ть
• но́вые
• слова́
• у́тром

A rough pronunciation guide for English speakers:

• ya lyub-LYU pafta-RYAT NO-vy-ye sla-VA U-tram

The exact sounds are not identical to English, but the most important thing at first is learning the correct stress, because stress in Russian is very important and can move from word to word.
