אני רוצה לבלות עם המשפחה בבית בסוף השבוע.

Yes, Hebrew can sometimes omit the subject, but in the present tense it often keeps it for clarity.

The form רוצה tells you gender and number, but not clearly person. By itself, רוצה could mean:

• I want
• you want (masculine singular)
• he wants

So אני רוצה makes it clear that the subject is I.

In normal Hebrew spelling, both are written רוצה, but they are pronounced differently:

• רוֹצֶה = rotze = masculine singular
• רוֹצָה = rotza = feminine singular

So:

• a male speaker says אני רוצה = ani rotze
• a female speaker says אני רוצה = ani rotza

This is very common in Hebrew: the unpointed spelling looks the same, but the pronunciation changes.

Because after רוצה = want, Hebrew normally uses the infinitive of the next verb.

So the pattern is:

• רוצה + infinitive
• want + to + verb

Examples:

• אני רוצה לאכול = I want to eat
• אני רוצה לישון = I want to sleep
• אני רוצה לבלות = I want to spend time / hang out

The ל־ here is the normal marker of the Hebrew infinitive.

Here לבלות means something like:

• to spend time
• to hang out
• to enjoy oneself

So in this sentence it means to spend time with the family.

It does not usually mean to spend in every English sense. For example:

• spend money is not normally לבלות כסף
• for spend time pleasantly, לבלות is very natural

So this verb has a more social/leisure feeling than the English verb spend.

המשפחה means the family.

In Hebrew, when people talk about their own family, they often say עם המשפחה if the context already makes it obvious whose family they mean. English often prefers my family, but Hebrew does not always need to say that.

So:

• עם המשפחה = with the family / with my family / with our family, depending on context
• עם המשפחה שלי = with my family, more explicit
• עם משפחה sounds more indefinite, like with a family, and is less natural here

Because המשפחה is not a direct object here.

The word את is used before a definite direct object. But in this sentence, המשפחה comes after the preposition עם = with, so it is part of a prepositional phrase, not a direct object.

Compare:

• אני אוהב את המשפחה = I love the family

  • here המשפחה is a direct object, so you need את

• אני מבלה עם המשפחה = I spend time with the family

  • here המשפחה comes after עם, so no את

Because בבית means at home / in the house, while הביתה means homeward / to home.

Use בבית when you are talking about a location where someone is staying:

• אני בבית = I am at home
• אני רוצה לבלות בבית = I want to spend time at home

Use הביתה when there is movement toward home:

• אני הולך הביתה = I am going home

So in this sentence, the idea is spending time at home, not going home.

Literally, בסוף השבוע means at the end of the week.

But in everyday Modern Hebrew, it is also the normal way to say on the weekend or over the weekend.

So this phrase is very natural.

A small cultural note: in Israeli Hebrew, the weekend usually refers mainly to Friday–Saturday, not Saturday–Sunday as in many English-speaking places.

Because Hebrew often uses a structure called the construct state (in Hebrew: סמיכות) instead of של.

So:

• סוף השבוע = the end of the week / the weekend

This is more natural and compact than:

• הסוף של השבוע

The version with של is not impossible, but here it sounds less natural.

An important detail: in סוף השבוע, the first word סוף does not take ה־, even though the whole phrase is definite. The definiteness comes from השבוע.

Hebrew often attaches short prefixes directly to the following word.

In this sentence:

• לבלות has ל־ attached to the verb
• בבית has ב־ attached to בית
• בסוף has ב־ attached to סוף

This is completely normal in Hebrew.

Also, when ב־, ל־, or כ־ come before a word with ה־ (the), they often merge with it. For example:

• ב + הבית becomes בבית
  pronounced ba-bayit

But not every preposition attaches. For example:

• עם stays separate: עם המשפחה

The word order is not completely fixed. Hebrew is more flexible than English here.

The original sentence is very natural:

• אני רוצה לבלות עם המשפחה בבית בסוף השבוע.

But these are also possible:

• אני רוצה לבלות בבית עם המשפחה בסוף השבוע.
• בסוף השבוע אני רוצה לבלות עם המשפחה בבית.

Changing the order usually changes emphasis, not the basic meaning.

A simple rule: the given version sounds neutral and natural, so it is a good model to learn first.
