כשהוא חוזר הביתה, הוא שותה תה חם.

כשהוא means when he.

It is made from:

• כש־ = when / as
• הוא = he

So כשהוא חוזר הביתה literally starts as when he returns home.

In everyday Hebrew, כש־ is very common. A more formal version would be כאשר הוא.

Because Hebrew often uses the present tense for habitual or general actions.

So this sentence most naturally describes a routine:

• When he gets home, he drinks hot tea
• Whenever he comes home, he drinks hot tea

Hebrew present tense does a lot of work that English divides into different forms, such as:

• he drinks
• he is drinking
• sometimes even a habitual he usually drinks

The exact meaning depends on context.

Most naturally, it describes a habit or repeated action.

So the sense is:

• When he comes home, he drinks hot tea
• Whenever he gets home, he drinks hot tea

If you wanted a one-time future meaning, Hebrew would usually use the future tense, for example:

• כשהוא יחזור הביתה, הוא ישתה תה חם
  = When he comes back home, he will drink hot tea

Because the second clause needs its own subject:

• כשהוא חוזר הביתה = when he returns home
• הוא שותה תה חם = he drinks hot tea

Also, in Hebrew present tense, the verb usually does not show person clearly by itself. A form like שותה can mean I drink, you drink, or he drinks, depending on context. So using הוא makes the subject explicit.

Repeating the pronoun here is completely natural.

Yes. In the present tense, Hebrew verbs agree with the subject in gender and number.

Here the subject is הוא, so the verbs are masculine singular:

• חוזר = masculine singular returns
• שותה = masculine singular drinks in this sentence

If the subject were she, you would say:

• כשהיא חוזרת הביתה, היא שותה תה חם

Notice that חוזרת changes clearly, while שותה may look the same in ordinary unpointed spelling.

הביתה means home / to the house / homeward.

The final ־ה is an old directional ending that means something like to or toward a place. So:

• בית = house
• הביתה = homeward / to the house / home

In modern Hebrew, לחזור הביתה is the normal expression for to return home or to go back home.

You may also see this directional ending in a few other words, such as:

• החוצה = outside / out
• העירה = to the city

Because Hebrew has no indefinite article.

So תה חם can mean:

• hot tea
• a hot tea
• sometimes some hot tea

The meaning comes from context.

Hebrew only marks the, using ה־:

• תה חם = hot tea
• התה החם = the hot tea

Because את is used only before a definite direct object.

Here, תה חם is indefinite, so there is no את:

• הוא שותה תה חם = he drinks hot tea

But if it were definite, you would use את:

• הוא שותה את התה החם = he drinks the hot tea

So the rule is:

• indefinite object → no את
• definite object → use את

Because in Hebrew, adjectives normally come after the noun.

So:

• תה חם = hot tea
• בית גדול = big house
• ילד טוב = good boy

The adjective also agrees with the noun in:

• gender
• number
• definiteness

That is why the hot tea becomes:

• התה החם

Both words take ה־ when the phrase is definite.

Not exactly word for word.

חוזר literally means returns / comes back / goes back.
So חוזר הביתה is more literally returns home or goes back home.

In natural English, though, this is often translated as comes home, because that is what sounds normal in the situation.

So the Hebrew idea is returning, even if the English translation uses come.

Yes.

The given sentence starts with the when clause:

• כשהוא חוזר הביתה, הוא שותה תה חם.

This is very natural and puts the time setting first.

You could also say:

• הוא שותה תה חם כשהוא חוזר הביתה.

That version is also grammatical, but it sounds a little more like the main point is he drinks hot tea, with the time detail added afterward.

In standard writing, yes, the comma is normal after an opening subordinate clause like כשהוא חוזר הביתה.

So:

• כשהוא חוזר הביתה, הוא שותה תה חם.

That is the standard written form.

In very casual writing or texting, people may sometimes leave the comma out, but using it here is correct and helpful.

A simple transliteration is:

kshehu khozer habayta, hu shote te kham

A few pronunciation notes:

• כשהוא sounds roughly like kshe-hu
• ח in חוזר and חם is the throaty kh/ch sound
• תה is simply te
• הביתה is pronounced roughly ha-BAY-ta

So the whole sentence is approximately:

kshehu khozer habayta, hu shote te kham
