לפעמים הוא הולך עם חבר, אבל לפעמים הוא הולך לבד.

לפעמים means sometimes and functions as an adverb of frequency.

In this sentence, it appears at the beginning of each clause:

לפעמים הוא הולך... אבל לפעמים הוא הולך...

That placement is very natural, because it sets the time pattern right away.

You can sometimes move it, for example:

הוא לפעמים הולך עם חבר

but the version with לפעמים at the front is usually smoother and more common in simple sentences like this.

הולך is the masculine singular present-tense form of the verb ללכת.

Even though it is a present form, Hebrew uses the present tense for both:

• a general habit, like English he goes
• an action happening now, like English he is going

Here, because of לפעמים, the meaning is clearly habitual, so הולך is understood as goes rather than is going.

In Modern Hebrew, the present tense is built from forms that historically behave like participles, but in everyday use they serve as normal present-tense verb forms.

So הוא הולך can mean:

• he goes
• he is going
• sometimes even he walks, depending on context

In this sentence, the context of repeated לפעמים makes it mean he sometimes goes.

Because the sentence has two full clauses joined by אבל:

• לפעמים הוא הולך עם חבר
• אבל לפעמים הוא הולך לבד

Repeating הוא is completely normal and sounds clear and natural in Hebrew.

Technically, Hebrew can sometimes omit repeated material if it is obvious, but with a contrast like this, repeating the subject is very common and often preferred.

Yes, it could sometimes be left out in casual speech if the meaning is obvious, but repeating it is the most complete and standard version.

Full version:

לפעמים הוא הולך עם חבר, אבל לפעמים הוא הולך לבד.

Shorter version:

לפעמים הוא הולך עם חבר, אבל לפעמים לבד.

The full version sounds balanced and clear, especially for learners.

עם חבר means with a friend or with some friend in a general sense.

There is no ה on חבר, so it is indefinite.

If you said עם החבר, that would mean with the friend, referring to a specific known friend.

So:

• עם חבר = with a friend
• עם החבר = with the friend

חבר most commonly means friend, but in some contexts it can also mean boyfriend.

However, in a simple sentence like this, especially without extra context, learners should understand it as friend.

If Hebrew wants to be especially clear, it can say things like:

• חבר טוב = a good friend
• בן זוג = partner
• חבר שלו = his friend

עם is the preposition with.

So:

• עם חבר = with a friend

It is a very common preposition in Hebrew.

Be careful not to confuse this עם meaning with with another Hebrew word spelled the same way, עם, meaning people or nation. The meaning depends on context.

לבד means alone or by oneself.

In this sentence, it works like an adverb or complement describing how he goes:

• הוא הולך לבד = he goes alone

In everyday Modern Hebrew, לבד is very common and usually stays the same. You may also meet more literary or formal forms like:

• לבדו = by himself
• לבדה = by herself

But לבד is the normal everyday choice.

You would change the subject and the present-tense verb form:

• הוא הולך = he goes
• היא הולכת = she goes

So the sentence would become:

לפעמים היא הולכת עם חבר, אבל לפעמים היא הולכת לבד.

If you specifically wanted with a female friend, you could say:

עם חברה

So one possible version is:

לפעמים היא הולכת עם חברה, אבל לפעמים היא הולכת לבד.

Because the subject is הוא, meaning he.

In Hebrew present tense, the verb agrees with the subject in gender and number.

So:

• הוא הולך = he goes
• היא הולכת = she goes
• הם הולכים = they go, masculine or mixed group
• הן הולכות = they go, feminine group

Since the sentence uses הוא, the correct form is הולך.

A common pronunciation guide is:

lif'amim hu holekh im khaver, aval lif'amim hu holekh levad

A few useful notes:

• לפעמים = lif'amim
• הולך ends with a rough kh sound
• חבר also has that rough kh sound: khaver
• אבל = aval
• לבד = levad

A natural rhythm would be:

lif'amim hu holekh im khaver, aval lif'amim hu holekh levad
