היא יודעת איפה האוטו.

A common pronunciation is:

Hi yoda'at eifo ha-oto.

A rough stress guide:

• hi
• yo-DA-at
• EI-fo
• ha-O-to

In fast everyday speech, יודעת is often pronounced a bit more smoothly, almost like yodat, but the full form is still yoda'at.

Word by word:

• היא = she
• יודעת = knows
• איפה = where
• האוטו = the car

So the structure is literally something like:

She knows where the car.

But in natural English, that means:

She knows where the car is.

Because the subject is היא, which means she.

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

• היא יודעת = she knows
• הוא יודע = he knows

So יודעת is the feminine singular present-tense form of לדעת (to know).

Because in Hebrew, the verb to be is usually omitted in the present tense.

So:

• האוטו פה = the car is here
• איפה האוטו = where is the car? / where the car is

Hebrew often leaves out is / am / are in present-tense sentences. That is completely normal.

Because האוטו is not the direct object of יודעת here.

The verb יודעת is followed by an entire clause:

איפה האוטו = where the car is

So she does not directly know the car; she knows where the car is.

You use את only before a definite direct object, not before a noun that is part of a where... clause.

Yes. איפה means where.

It is often used in direct questions:

• איפה האוטו? = Where is the car?

But it can also introduce an embedded clause, as in this sentence:

• היא יודעת איפה האוטו. = She knows where the car is.

So here איפה is not asking the listener a question directly; it is part of what she knows.

The ה־ is the Hebrew definite article, meaning the.

So:

• אוטו = a car / car
• האוטו = the car

In Hebrew, the is usually attached directly to the noun as a prefix.

No. אוטו is a very common everyday word for car.

Another common word is:

• מכונית = car

So you could also hear:

• היא יודעת איפה המכונית.

But האוטו sounds very natural and common in spoken Hebrew.

Yes.

• איפה = very common, everyday where
• היכן = also where, but usually a bit more formal or literary

So both are grammatical:

• היא יודעת איפה האוטו.
• היא יודעת היכן האוטו.

In normal speech, איפה is more common.

It would be:

הוא יודע איפה האוטו.

That means He knows where the car is.

Compare:

• היא יודעת = she knows
• הוא יודע = he knows

With ניקוד, it can be written as:

הִיא יוֹדַעַת אֵיפֹה הָאוֹטוֹ.

In everyday modern Hebrew, vowel marks are usually omitted, so you will normally see:

היא יודעת איפה האוטו.

Because לדעת and להכיר are used differently.

• לדעת = to know a fact, piece of information, answer, location, etc.
• להכיר = to know / be familiar with a person, place, or thing

Here the sentence is about knowing information: the location of the car.

So:

• היא יודעת איפה האוטו. = correct

Using מכירה here would not fit the meaning.
