Jetzt ist die Straße wieder frei.

Because German main clauses usually follow the verb-second rule.

In Jetzt ist die Straße wieder frei:

• Jetzt = first position
• ist = second position
• die Straße wieder frei = the rest of the sentence

So even though English says Now the street is free again, German puts the finite verb ist right after the first element.

A useful way to think of it is:

• Jetzt | ist | die Straße | wieder frei

If you move something else to the front, ist still stays second:

• Die Straße ist jetzt wieder frei.

Both are correct.

Starting with Jetzt puts special focus on now.

It suggests a contrast such as:

• before, the street was blocked
• now, it is free again

German often moves time words like jetzt, heute, dann, or morgen to the front for emphasis. It does not change the basic meaning much, but it changes what the speaker highlights.

Compare:

• Jetzt ist die Straße wieder frei. = emphasis on now
• Die Straße ist jetzt wieder frei. = more neutral

Die Straße is in the nominative case because it is the subject of the sentence.

The verb sein (ist) links the subject to a description:

• die Straße = the thing being described
• frei = the description

So the structure is basically:

• The street = subject
• is = linking verb
• free = predicate adjective

Since Straße is feminine, the nominative singular article is die.

Straße is a feminine noun in German.

So in the singular:

• die Straße = nominative / accusative singular
• der Straße = genitive / dative singular

You simply have to learn the noun together with its article:

• die Straße = the street / road

This is very important in German, because the article helps show gender and case.

Here, wieder means again.

So wieder frei means:

• free again
• clear again
• open again, depending on context

It tells us that the street was free before, then it was not free, and now it has returned to that state.

A very literal breakdown would be:

• Jetzt = now
• ist = is
• die Straße = the street
• wieder = again
• frei = free / clear

Frei is a predicate adjective here. It comes after the verb sein and describes the subject.

In German, predicate adjectives do not take adjective endings.

So you say:

• Die Straße ist frei.
• Der Platz ist voll.
• Das Fenster ist offen.

But when an adjective comes before a noun, it usually does take an ending:

• die freie Straße
• ein freier Platz
• das offene Fenster

So:

• die freie Straße = the free/clear street (adjective before noun)
• die Straße ist frei = the street is free (predicate adjective, no ending)

Yes. Several word orders are possible, depending on emphasis.

Common versions include:

• Jetzt ist die Straße wieder frei.
• Die Straße ist jetzt wieder frei.
• Jetzt ist wieder die Straße frei. (possible, but more marked and less neutral)

The most neutral versions are usually:

• Die Straße ist jetzt wieder frei.
• Jetzt ist die Straße wieder frei.

What stays fixed in a normal main clause is that the finite verb ist must be in second position.

Because frei is just an adjective, not a noun.

In this sentence:

• die Straße = the noun phrase
• frei = the adjective describing it

German does not use an article before predicate adjectives:

• Die Straße ist frei.
• Das Zimmer ist sauber.
• Das Essen ist gut.

So this is completely normal.

Yes, but in context it usually means something like:

• clear
• open
• unblocked
• free of traffic/obstacles

German frei has a broad range of meanings, just like English free. In road or traffic contexts, it often means that something is no longer blocked.

So depending on context, Die Straße ist wieder frei could naturally be understood as:

• The road is clear again.
• The street is open again.

Straße is pronounced roughly like SHTRAH-suh.

A few details:

• Str at the start of a word in standard German is usually pronounced like shtr
• ß is called Eszett or scharfes S
• ß represents a voiceless s sound, like the s in see, not a z sound
• the a in Stra- is long: Stra-
• the final e is a soft uh sound

So:

• Straße ≈ SHTRAH-suh

Also, ß never begins a word and is not the same as B.

Because all nouns are capitalized in German.

So:

• die Straße
• das Haus
• der Mann
• die Freiheit

This is one of the most noticeable spelling rules in German. Adjectives like frei are normally not capitalized unless they begin the sentence or are being used as nouns.

Often, yes, but not always in tone.

Both can mean now, but:

• jetzt is the most common everyday word
• nun can sound a bit more formal, literary, or sometimes more pointed depending on context

So you could say:

• Nun ist die Straße wieder frei.

But Jetzt ist die Straße wieder frei sounds more everyday and natural for most situations.

The structure is:

• Jetzt = adverb of time
• ist = finite verb, from sein
• die Straße = subject, nominative
• wieder = adverb
• frei = predicate adjective

So the pattern is:

time expression + verb + subject + adverb + adjective

A more underlying, learner-friendly version is:

• Die Straße ist wieder frei. = The street is free again.
• Jetzt is placed first for emphasis, which forces ist into second position.

It is most naturally understood literally: a street or road is no longer blocked.

For example:

• after an accident is cleared
• after construction ends
• after police reopen the road

But German frei can also be used in many other expressions, so in different contexts it can sound broader. In this specific sentence, though, the everyday interpretation is very likely:

• The street/road is open again
• The street/road is clear again
