הכלב רץ לתוך הבית.

A common pronunciation is:

ha-kelev ratz le-tokh ha-bayit

A rough breakdown:

• הכלב = ha-kelev = the dog
• רץ = ratz = runs / is running
• לתוך = le-tokh = into
• הבית = ha-bayit = the house

Notes:

• ח / כ in לתוך is a throaty sound that English does not really have. Many learners approximate it with a soft kh sound.
• ץ at the end of רץ sounds like ts.

Because Hebrew adds the definite article ה־ to the beginning of a noun.

So:

• כלב = dog
• הכלב = the dog

This ה־ is the Hebrew equivalent of English the.

It can mean either one, depending on context.

In modern Hebrew, the present tense often covers both:

• he runs
• he is running

So הכלב רץ לתוך הבית can mean:

• The dog runs into the house
• The dog is running into the house

English makes a stronger distinction between simple present and present progressive than Hebrew does.

Because the verb has to agree with the subject in gender and number.

The subject here is הכלב (the dog), which is grammatically:

• masculine
• singular

So the present-tense form is רץ.

Compare:

• רץ = masculine singular
• רצה = feminine singular
• רצים = masculine plural
• רצות = feminine plural

So if you changed the subject, the verb would change too.

Not necessarily in real life, but grammatically it is treated as masculine.

The noun כלב is a masculine noun in Hebrew, so the verb agrees with it in the masculine singular form: רץ.

If you specifically used the feminine noun כלבה (female dog), you would normally say:

• הכלבה רצה לתוך הבית

So the verb form reflects grammatical gender.

לתוך means into or to the inside of.

It shows movement from outside to inside.

So:

• לתוך הבית = into the house

This is more specific than just saying to the house. It emphasizes entering the inside.

Good question. Both can sometimes be translated similarly, but there is a nuance.

• לבית = to the house / homeward / into the house in some contexts
• לתוך הבית = into the house, more explicitly

לתוך clearly stresses movement inward, into the interior space.

So:

• הכלב רץ לבית can sound a bit more general
• הכלב רץ לתוך הבית clearly means the dog ran into the inside of the house

Because the English meaning is the house, not just a house or house.

So:

• בית = house
• הבית = the house

Hebrew marks definiteness directly on the noun with ה־.

Because Hebrew usually does not use a separate word for is/am/are in the present tense.

English says:

• The dog is running into the house

Hebrew simply says:

• הכלב רץ לתוך הבית

That is completely normal Hebrew. The present-tense verb form itself does the job.

Because הבית is not a direct object here. It is the destination of movement, introduced by the preposition לתוך.

את is used before a definite direct object, for example:

• הכלב רואה את הבית = The dog sees the house

But in your sentence:

• לתוך הבית = into the house

That is a prepositional phrase, not a direct object, so את is not used.

The basic order here is very natural:

• הכלב = subject
• רץ = verb
• לתוך הבית = prepositional phrase

So the sentence is:

• Subject + Verb + Destination

This is a common and neutral word order in modern Hebrew.

Hebrew word order can sometimes change for style, emphasis, or literary effect, but הכלב רץ לתוך הבית is the most straightforward version.

Yes. It is completely normal in both spoken and written modern Hebrew.

It sounds natural, clear, and simple. A learner can treat it as a standard everyday sentence pattern:

• [subject] + [present-tense verb] + [prepositional phrase]

For example:

• הילד רץ לתוך החדר = The boy runs/is running into the room
• החתול קפץ לתוך הקופסה = The cat jumped into the box
