Die Firma arbeitet weltweit.

Firma is a feminine noun in German, so its basic article is die.

In this sentence, die Firma is also the subject, so it is in the nominative case:

• die Firma = the company

The other forms would appear in different grammatical situations:

• der Firma = dative or genitive singular, depending on context

So here, die Firma is correct because the company is the one doing the action.

In German, all nouns are capitalized. So Firma must begin with a capital letter.

This is different from English, where common nouns like company are usually lowercase.

arbeitet is the 3rd person singular present tense form of arbeiten, which means to work.

The verb forms are:

• ich arbeite
• du arbeitest
• er/sie/es arbeitet
• wir arbeiten
• ihr arbeitet
• sie/Sie arbeiten

Because die Firma is grammatically singular, the verb must be arbeitet.

In this sentence, arbeitet can sound slightly more natural in English as operates or does business, depending on context, even though the basic meaning is works.

Because Firma is grammatically singular.

German agrees the verb with the grammatical subject, not with the number of people inside the company. So:

• Die Firma arbeitet ... = singular
• Die Firmen arbeiten ... = plural

This is similar to English The company works/operates worldwide.

Here, weltweit is an adverb. It describes how or where the company works: worldwide, globally.

So:

• Die Firma arbeitet weltweit. = The company operates worldwide.

weltweit can also be used as an adjective in other sentences, for example:

• ein weltweit bekanntes Unternehmen = a company known worldwide

Because weltweit already works on its own as an adverb meaning worldwide or globally.

English sometimes uses a phrase like around the world, but German can simply say:

• weltweit

So you do not need something like in weltweit here.

Compare:

• Die Firma arbeitet weltweit. = The company operates worldwide.
• Die Firma arbeitet in Europa. = The company operates in Europe.

With Europa, you need a preposition. With weltweit, you do not.

Yes. The sentence follows the very common German pattern:

• subject + verb + adverbial

So:

• Die Firma = subject
• arbeitet = verb
• weltweit = adverb

This is the most neutral word order.

You can change the order for emphasis, but then the verb still stays in second position:

• Weltweit arbeitet die Firma.

That version is possible, but it is less neutral and puts more emphasis on weltweit.

Yes, absolutely. That is a very common alternative.

• Die Firma arbeitet weltweit.
• Die Firma ist weltweit tätig.

Both can mean that the company operates worldwide.

However, ist weltweit tätig often sounds a bit more formal or business-like. You may see it often in company descriptions or on websites.

Both can often be translated as company, but they are not always identical in tone.

• Firma is very common in everyday German.
• Unternehmen can sound a bit more formal or broader, like business or enterprise.

In many simple contexts, either works:

• Die Firma arbeitet weltweit.
• Das Unternehmen arbeitet weltweit.

But Firma is perfectly natural here.

Yes. In German, the present tense is often used for:

• things happening now
• regular actions
• general facts

So Die Firma arbeitet weltweit usually means a general current fact: the company operates worldwide.

It does not necessarily mean that the company is doing something worldwide at this exact moment.

A simple pronunciation guide is:

dee FIR-ma AR-bye-tet VELT-vyte

A few useful points:

• die sounds like dee
• Firma has stress on the first syllable: FIR-ma
• arbeitet has stress near the beginning: AR-bye-tet
• weltweit rhymes roughly with belt-vite, with v pronounced like English f in this word

If you want to sound natural, keep the stress especially on:

• FIR in Firma
• AR in arbeitet
• WELT in weltweit
