בלילה הרחוב שקט.

בלילה means at night or during the night.

It is made from:

• ב־ = in / at
• לילה = night
• plus the definite article ה־ = the

So the full underlying idea is in the night. In Hebrew, ב־ and ה־ combine, so ב + הלילה becomes בלילה.

If you learn pointed Hebrew, you may see it as בַּלַּיְלָה.

Because in present-tense Hebrew, the verb to be is usually not stated.

So:

• הרחוב שקט = the street is quiet
• literally: the street quiet

This kind of sentence is called a nominal sentence.

In other tenses, Hebrew usually does use a form of to be:

• בלילה הרחוב היה שקט = At night the street was quiet
• בלילה הרחוב יהיה שקט = At night the street will be quiet

Hebrew often puts a time expression at the beginning of the sentence, especially when setting the scene.

So בלילה הרחוב שקט is very natural and means:

• At night, the street is quiet

You could also say:

• הרחוב שקט בלילה

That has the same basic meaning, but the version starting with בלילה puts a little more focus on when this is true.

הרחוב means the street.

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

So:

• רחוב = a street / street
• הרחוב = the street

In this sentence, the subject is definite: the street.

Because שקט here is a predicate adjective, not part of the noun phrase.

Compare:

• הרחוב שקט = the street is quiet
• הרחוב השקט = the quiet street

That is a very important difference in Hebrew:

• noun + adjective with no is → sentence: the street is quiet
• noun + adjective, both definite → noun phrase: the quiet street

So שקט has no ה־ because it is saying something about the street, not naming a type of street.

Adjectives in Hebrew usually agree with the noun in gender and number.

רחוב is:

• masculine
• singular

So the adjective is also masculine singular:

• שקט = quiet (masculine singular)

Compare:

• העיר שקטה = the city is quiet
  because עיר is feminine singular, so the adjective becomes שקטה

• הרחובות שקטים = the streets are quiet
  because streets is masculine plural, so the adjective becomes שקטים

It is a complete sentence.

Its parts are:

• בלילה = time expression: at night
• הרחוב = subject: the street
• שקט = predicate adjective: quiet

So the structure is:

• At night
  • the street
    • quiet

Even though English needs is, Hebrew does not in the present tense, so nothing is missing.

Yes. That is a perfectly natural English translation.

Because Hebrew word order is more flexible than English, בלילה הרחוב שקט and הרחוב שקט בלילה can both correspond to:

• The street is quiet at night
• At night, the street is quiet

The difference is mainly one of focus or style, not core meaning.

A simple pronunciation guide is:

ba-LAI-la ha-reKHOV sha-KET

A few notes:

• בלילה = ba-LAI-la
• הרחוב = ha-reKHOV
• שקט = sha-KET

The ch / kh sound in הרחוב is the throaty Hebrew sound of ח, not an English ch as in chair.

Not necessarily.

In many contexts, בלילה means at night in a general sense, as in:

• At night, the street is quiet

Depending on context, it can also refer to during the night or in the nighttime.

So the exact nuance comes from the situation, but in a basic sentence like this, learners usually understand it as a general statement about nighttime.
