Wir sind fast zu Hause.

Because sind is the correct conjugated form of sein for wir.

The verb sein changes depending on the subject:

• ich bin
• du bist
• er/sie/es ist
• wir sind
• ihr seid
• sie/Sie sind

So Wir sind ... means we are ...

Fast means almost or nearly.

In this sentence, it modifies zu Hause, so the idea is we are almost at home.

Compare:

• Wir sind zu Hause. = We are at home.
• Wir sind fast zu Hause. = We are almost at home.

So fast tells you that the situation is not fully true yet, but very close.

Zu Hause is a fixed expression meaning at home.

You should learn it as a set phrase. It does not literally work like English to house. In modern German, zu Hause means being at home, in the sense of location.

That is why German says:

• Ich bin zu Hause. = I am at home.
• Wir sind fast zu Hause. = We are almost at home.

You would not normally say Wir sind fast im Haus unless you literally mean we are almost inside the building.

This is a very common question.

• zu Hause = at home → location
• nach Hause = home / to home → direction, movement toward home

So:

• Wir sind zu Hause. = We are at home.
• Wir gehen nach Hause. = We are going home.

In your sentence, sind describes where we are, so zu Hause is the right choice.

In zu Hause, the word Hause is part of an old fixed expression.

The -e is an older dative ending that still survives in a few set phrases. You do not usually add this -e to nouns in normal modern German, but some expressions kept it.

So learners usually just memorize:

• zu Hause
• nach Hause

as whole expressions.

Yes. In modern German, both zu Hause and zuhause are used.

For learners, zu Hause is often taught first because it clearly shows the old noun Haus inside the expression. It is very standard and completely correct.

So these are both possible:

• Wir sind fast zu Hause.
• Wir sind fast zuhause.

The version with a space is especially common in teaching materials.

Because it comes from the noun Haus, and nouns are capitalized in German.

Even though zu Hause functions like an adverbial expression meaning at home, it still keeps the noun capitalization in the traditional spelling.

That is why you see:

• zu Hause
• nach Hause

with a capital H.

A natural pronunciation is roughly:

Veer zint fahst tsoo HOW-zuh

A more accurate guide:

• Wir sounds like veer
• sind sounds like zint or zind depending on accent
• fast has a short a, not like English paste
• zu sounds like tsoo
• Hause sounds like HOW-zuh

The stress is mainly on fast and Hau- in normal speech: Wir sind fast zu HAUse.

Yes. Beinahe is very similar to fast and also means almost or nearly.

So both are possible:

• Wir sind fast zu Hause.
• Wir sind beinahe zu Hause.

In everyday speech, fast is usually more common and a little more natural in a short sentence like this.

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

In a normal statement, the conjugated verb comes in the second position:

• Wir sind fast zu Hause.

Here:

1. Wir
2. sind

That is standard German word order.

You can also move another element to the front, but then the verb still stays second:

• Fast sind wir zu Hause.

That version is possible, but Wir sind fast zu Hause is the most neutral and natural order.
