הנה, הגרר מגיע.

The prefix ה־ is the Hebrew definite article, the equivalent of the in English. Hebrew attaches the directly to the noun instead of writing it as a separate word.

With vowels, this part would be written הַגְּרָר.

Hebrew normally does not use a separate present-tense word for to be in sentences like this. The form מגיע already expresses the present-time idea.

So Hebrew says הגרר מגיע, while natural English says the tow truck is coming or is arriving.

מגיע is the masculine singular present form of the verb להגיע, meaning to arrive / to reach. In Modern Hebrew, these present forms are used where English often uses either the simple present or the present progressive.

So מגיע can mean:

• arrives
• is arriving
• is coming

The exact English translation depends on context.

Because הגרר is a masculine singular noun, and the present form has to agree with it.

• masculine singular: מגיע
• feminine singular: מגיעה
• masculine plural: מגיעים
• feminine plural: מגיעות

So הגרר מגיע is the correct agreement.

Roughly ma-gi-a. It has three syllables, not two. The final letter ע creates a separate syllable, even though in modern Israeli Hebrew it is often only weakly pronounced.

So learners should avoid pronouncing it like a two-syllable word such as magya.

Because הנה is being used like an interjection or discourse marker, similar to look or there in English. The comma shows a short pause before the main clause.

So the rhythm is something like: הנה, | הגרר מגיע

In informal writing, punctuation may vary, but the comma is very natural here.

No. After הנה, the clause הגרר מגיע is a normal and natural subject + verb order: the tow truck is arriving.

What makes the sentence feel a little more vivid is הנה at the beginning, because it draws the listener’s attention to what is happening.
