Der Flachbettscanner digitalisiert das Negativ.

Because German nouns have grammatical gender, and the article has to match the noun.

• der Flachbettscanner = masculine
• das Negativ = neuter

In this sentence, both nouns are also in the nominative/accusative forms that happen to look like this:

• der Flachbettscanner is the subject
• das Negativ is the direct object

Unlike English, you usually have to learn each noun together with its article:

• der Scanner
• das Negativ

Since Flachbettscanner is a kind of Scanner, it keeps the same gender: der.

The subject is der Flachbettscanner, because it is the thing doing the action.

The object is das Negativ, because it is the thing being digitalized.

So the structure is:

• Der Flachbettscanner = subject
• digitalisiert = verb
• das Negativ = direct object

This is the normal German word order for a basic statement: subject + verb + object.

Because digitalisieren is the infinitive form, like English to digitize.

In the sentence, the verb is conjugated to match the subject:

• ich digitalisiere
• du digitalisierst
• er/sie/es digitalisiert
• wir digitalisieren
• ihr digitalisiert
• sie/Sie digitalisieren

Since der Flachbettscanner is a third-person singular subject, the correct form is digitalisiert.

Yes. German very often combines nouns into a single compound word.

Flachbettscanner is made of:

• Flachbett = flatbed
• Scanner = scanner

So Flachbettscanner literally means flatbed scanner.

This is completely normal in German. English often writes similar ideas as two words, but German often writes them as one:

• Haus + Tür = Haustür
• Computer + Bildschirm = Computerbildschirm

The last part usually determines the grammatical gender and the basic meaning. Here, the last part is Scanner, so the whole word is masculine: der Flachbettscanner.

Because all nouns are capitalized in German.

So in this sentence:

• Flachbettscanner is capitalized because it is a noun
• Negativ is capitalized because it is a noun

The verb digitalisiert is not capitalized because it is not a noun.

This is one of the most noticeable spelling differences between German and English.

German main clauses usually follow the verb-second rule (V2). That means the finite verb goes in the second position.

In this sentence:

• Position 1: Der Flachbettscanner
• Position 2: digitalisiert
• Then: das Negativ

So the sentence follows a standard German main-clause pattern.

You could also move something else to the front, but the verb would still stay second:

• Das Negativ digitalisiert der Flachbettscanner.

That sounds more marked or emphatic, but it is still grammatical because digitalisiert remains in second position.

It is in the accusative case, because it is the direct object of the verb digitalisieren.

The verb digitalisieren normally takes a direct object:

• digitalize something

So:

• der Flachbettscanner = nominative subject
• das Negativ = accusative object

In this particular sentence, das looks the same in nominative and accusative for neuter nouns, so the form does not change.

Because it is the subject, so it stays in the nominative case.

For a masculine noun, the article der is correct in the nominative:

• der Scanner

If it were a masculine direct object, it would usually change to den:

• Ich sehe den Scanner.

But here, the scanner is doing the action, not receiving it, so it remains der Flachbettscanner.

Yes. That would also be correct.

The difference is:

• Der Flachbettscanner = the flatbed scanner
• Ein Flachbettscanner = a flatbed scanner

So the original sentence sounds like it refers to a specific scanner, while ein would introduce one more generally.

Yes, it is a normal word, especially in photography or film contexts.

Here das Negativ means a photographic negative, not a negative opinion or a grammatical negative.

German often uses the same word:

• das Negativ = the negative
• das Foto = the photo
• der Film = the film

So the sentence sounds like something from photography, scanning, or archiving.

The plurals are:

• der Flachbettscanner → die Flachbettscanner
• das Negativ → die Negative

Examples:

• Die Flachbettscanner sind schnell.
• Der Flachbettscanner digitalisiert die Negative.

Notice that plural articles become die for both nouns.

No. digitalisieren is not separable.

So it stays together:

• Der Flachbettscanner digitalisiert das Negativ.
• Er hat das Negativ digitalisiert.

Some German verbs split in certain forms, like einscannen:

• Er scannt das Bild ein.

But digitalisieren does not split.

Sometimes yes, but the meaning is not always exactly the same.

• scannt focuses on the act of scanning
• digitalisiert focuses on converting something into a digital form

In many contexts, especially with a scanner, they may overlap:

• Der Flachbettscanner scannt das Negativ.
• Der Flachbettscanner digitalisiert das Negativ.

But digitalisieren can be a little broader or more formal, while scannen is often the more everyday technical verb for using a scanner.

Roughly:

FLAKH-bet-skan-er

A few helpful points:

• ch in Flach is the German ach sound, not like English ch in chair
• Scanner is pronounced similarly to English scanner, though with a German accent
• German compounds are usually stressed strongly near the beginning, so FLACH gets the main stress

You do not pronounce it as separate English-style words; it flows as one compound noun.
