Мне легче произнести трудное слово, когда я делю его на слоги.

Because Russian often uses a pattern that literally works like:

To me it is easier to pronounce...

So мне легче means it is easier for me.

• я = I
• мне = to me / for me (dative case)

This is a very common Russian structure for talking about feelings, states, or ease/difficulty:

• Мне трудно = It is hard for me
• Мне интересно = It is interesting to me
• Мне легче = It is easier for me

English usually uses I, but Russian often prefers this dative + predicative word structure.

Легче is the comparative form of легко.

• легко = easily / easy
• легче = more easily / easier

So мне легче произнести means it is easier for me to pronounce.

In this sentence, легче does not mean that something is physically lighter. It means easier in the sense of less difficult.

Compare:

• Это легко = This is easy
• Это легче = This is easier
• Мне легче читать утром = It’s easier for me to read in the morning

Because after words like легче, трудно, можно, нельзя, Russian often uses an infinitive to say what is easy/hard/possible/impossible to do.

So:

• Мне легче произнести слово = It is easier for me to pronounce the word

This is very natural Russian structure.

Other examples:

• Мне трудно понять = It is hard for me to understand
• Ему легко запомнить = It is easy for him to memorize
• Нам полезно знать = It is useful for us to know

Произнести is perfective, while произносить is imperfective.

Here the sentence is talking about successfully pronouncing a word as a complete action: to pronounce the word. That makes the perfective verb произнести natural.

Very roughly:

• произносить = to pronounce, be pronouncing, pronounce repeatedly/in general
• произнести = to pronounce once, to manage to pronounce, to say fully

In this sentence, the idea is: It’s easier for me to pronounce a difficult word when... That points to a completed result, so произнести fits well.

If you used произносить, it would sound more like a general ongoing process or habitual action.

Произнести specifically focuses on pronouncing or uttering something, often with attention to how it sounds.

• произнести слово = pronounce a word
• сказать слово = say a word
• говорить = speak / be speaking

In this sentence, the problem is about breaking a difficult word into syllables, so the issue is pronunciation. That is why произнести is the best choice.

So:

• сказать is about saying something
• говорить is about speaking
• произнести is about articulation/pronunciation

Because слово is:

• neuter
• singular
• accusative

And for an inanimate noun like слово, the accusative form is the same as the nominative.

The adjective трудное has to agree with слово in gender, number, and case.

So:

• трудный = masculine
• трудная = feminine
• трудное = neuter
• трудные = plural

Since слово is neuter singular, we get:

трудное слово

Because когда я делю его на слоги is a subordinate clause.

Russian uses commas before subordinate conjunctions like:

• когда = when
• если = if
• потому что = because
• что = that

So the sentence is divided into:

1. Мне легче произнести трудное слово
2. когда я делю его на слоги

The comma marks that the second part depends on the first.

This is normal Russian punctuation.

Делить на слоги is a standard, natural expression meaning to divide into syllables.

So:

• делить слово на слоги = to divide a word into syllables

Разделять can also mean divide, but in this context делить на слоги is the usual phrase learners should remember.

Examples:

• Ученики делят слова на слоги.
• Я делю длинные слова на слоги.

So this is not just any random use of делить; it is the normal collocation.

Because the fixed expression is:

делить что-то на что-то = to divide something into something

So:

• делю его на слоги = I divide it into syllables

Here на takes the accusative case:

• слоги is the accusative plural form of слог

Other similar examples:

• разделить текст на части = divide the text into parts
• делить торт на куски = divide the cake into pieces

So you should learn делить на + accusative as a pattern.

Его refers back to трудное слово.

So:

• слово = the difficult word
• его = it

Even though слово is neuter, Russian uses его for it in the accusative/genitive form.

That is completely normal:

• Я вижу слово. Я делю его на слоги. = I see the word. I divide it into syllables.

Because the sentence combines two different viewpoints:

• произнести focuses on a completed result: successfully pronouncing the word
• делю describes the method or process: I divide it into syllables

So the meaning is roughly:

It is easier for me to pronounce the word when I am dividing it into syllables / when I divide it into syllables.

This mixture is very common in Russian. The main action may be seen as a result, while the subordinate action describes an ongoing or repeated process.

Yes. Russian word order is flexible, although the original version is very natural:

Мне легче произнести трудное слово, когда я делю его на слоги.

You could also say:

• Когда я делю трудное слово на слоги, мне легче его произнести.
• Трудное слово мне легче произнести, когда я делю его на слоги.

These are all understandable, but they shift emphasis slightly.

The original sentence sounds neutral and natural: first the speaker states the main idea, then adds the condition.

Yes. Мне проще is very natural and common.

• Мне легче произнести трудное слово...
• Мне проще произнести трудное слово...

Both mean something like It’s easier for me to pronounce a difficult word...

The difference is small:

• легче often feels like the direct comparative of easy
• проще often feels like simpler / easier

In many everyday contexts, they are interchangeable.

Russian has no articles.

So трудное слово can mean:

• a difficult word
• the difficult word

The exact meaning depends on context.

In this sentence, English naturally says a difficult word, but Russian just says трудное слово.

This is something English speakers need to get used to: Russian usually leaves definiteness and indefiniteness unstated unless context makes it clear.

Yes.

• слог = syllable
• слоги = syllables

In this sentence, слоги is plural accusative, and for this inanimate noun that looks the same as the nominative plural.

So:

• nominative plural: слоги
• accusative plural: слоги

That is why you see на слоги.

A natural stress pattern would usually highlight легче, трудное слово, and possibly слоги, depending on what is important.

For example:

Мне легче произнести трудное слово, когда я делю его на слоги.

If the focus is on the method, на слоги may get stronger stress.

If the focus is on the difficulty of the word, трудное слово may stand out more.

Russian intonation is flexible, but the sentence as written sounds natural and conversational.
