הגרר כבר כאן.

ה־ is the Hebrew definite article, equivalent to the in English.

So:

• גרר = tow truck / tow vehicle (depending on context)
• הגרר = the tow truck

In Hebrew, ה־ is attached directly to the noun, not written as a separate word.

Because Hebrew usually leaves out to be in the present tense.

So הגרר כבר כאן literally looks like:

the tow truck already here

but it naturally means:

The tow truck is already here.

This is called a nominal sentence or verbless sentence in the present tense.

Compare:

• הגרר כבר כאן = The tow truck is already here
• הגרר היה כאן = The tow truck was here
• הגרר יהיה כאן = The tow truck will be here

In past and future, Hebrew does use forms of to be.

כבר usually means already.

In this sentence, it shows that the tow truck has arrived by now, often with the sense that this happened earlier than expected, or at least before some relevant point.

Examples:

• הוא כבר כאן = He’s already here
• אני כבר מוכן = I’m already ready
• כבר סיימתי = I already finished

So כבר is a very common everyday word.

כאן means here.

Yes, you can often say פה instead. Both are very common.

So these are both natural:

• הגרר כבר כאן
• הגרר כבר פה

A rough difference:

• כאן = a little more neutral or slightly more formal
• פה = very common in casual speech

But in normal conversation, either one works.

A simple pronunciation guide is:

ha-grar kvar kan

With stress roughly like this:

ha-grár kvár kan

If you want the fully pointed form, it is:

הַגְּרָר כְּבָר כָּאן

A few notes:

• כבר is pronounced kvar
• כאן is kan
• הגרר is pronounced with the ה־ attached: ha-grar

This is a very natural Hebrew word order:

subject + already + here

So:

• הגרר = the subject
• כבר = time-related adverb
• כאן = place adverb

Hebrew word order is somewhat flexible, but this version sounds neutral and natural.

For example:

• הגרר כבר כאן = neutral, natural
• הגרר כאן כבר = possible, but can sound like the speaker is emphasizing already
• כבר הגרר כאן = much less natural in ordinary speech

So the original sentence is the one a learner should treat as the standard version.

גרר is masculine.

You can see that in other sentences, for example:

• הגרר חדש = The tow truck is new
• הגרר הגיע = The tow truck arrived
• הוא כבר כאן = It/he is already here (using a masculine pronoun)

In הגרר כבר כאן, you do not actually see gender marking on כבר or כאן, because those words do not change for gender.

Yes. It is completely natural and complete.

Even though English requires is, Hebrew does not in the present tense, so native speakers fully understand this as a normal sentence.

This kind of sentence is extremely common in Hebrew:

• אני בבית = I’m at home
• הילדים בחוץ = The children are outside
• הקפה מוכן = The coffee is ready
• הגרר כבר כאן = The tow truck is already here

So yes — nothing is missing.

Yes. Depending on context, גרר can relate to towing and may refer to a tow truck, a towing vehicle, or sometimes something like a trailer in certain contexts.

In everyday speech, though, if people are talking about car trouble or roadside assistance, גרר is very often understood as tow truck.

If someone wants to be extra explicit, they might say:

משאית גרר = tow truck

But in ordinary conversation, גרר by itself is often enough.

A question is easy: in Hebrew, you can often just use intonation or a question mark.

• הגרר כבר כאן? = Is the tow truck already here?

For a negative, two common options are:

• הגרר לא כאן = The tow truck isn’t here
• הגרר עוד לא כאן = The tow truck isn’t here yet

Notice that עוד לא is often the most natural way to say not yet. So if you are contrasting with already here, עוד לא כאן is especially useful.
