Der Verdichter erhöht den Stromverbrauch.

Because Verdichter is the subject of the sentence, so it is in the nominative case: der Verdichter.

Stromverbrauch is the direct object of the verb erhöhen, so it is in the accusative case: den Stromverbrauch.

For masculine nouns in German, this change is very visible:

• nominative: der
• accusative: den

So the sentence structure is:

• Der Verdichter = the thing doing the action
• erhöht = increases
• den Stromverbrauch = the thing being increased

You usually have to learn the gender of each noun together with the noun itself. In this sentence, you can see that Verdichter is masculine because it uses der in the nominative: der Verdichter.

A good habit is to learn German nouns as a full unit:

• der Verdichter
• der Stromverbrauch

That is much better than memorizing only Verdichter or Stromverbrauch on their own.

The base form is erhöhen, which means to increase or to raise.

In the sentence, erhöht is the third-person singular present-tense form, used with der Verdichter:

• ich erhöhe
• du erhöhst
• er/sie/es erhöht
• wir erhöhen
• ihr erhöht
• sie/Sie erhöhen

So der Verdichter erhöht means the compressor increases.

Because the subject is third-person singular: der Verdichter = he/it.

In the present tense, regular verbs usually take -t with er/sie/es:

• erhöhen → er erhöht

So the ending matches the subject:

• Der Verdichter erhöht ...

Yes, it is one word because German very often forms compound nouns.

Stromverbrauch is made up of:

• Strom = electricity / electric current
• Verbrauch = consumption / usage

Together, Stromverbrauch means electricity consumption or power consumption.

This is very common in German. Instead of using several separate words the way English often does, German often joins them into one noun.

Because all nouns are capitalized in German.

That means:

• der Verdichter
• der Stromverbrauch

This is one of the easiest visual clues in German: if a word is capitalized in the middle of a sentence, it is often a noun.

You can tell from the case marking and the sentence structure.

Here:

• der Verdichter = nominative = subject
• den Stromverbrauch = accusative = direct object

So the compressor is doing the action, and the power consumption is receiving the action.

This is especially helpful in German because the articles often show the grammatical role more clearly than English does.

Yes. This is standard German main-clause word order:

• Subject
  • Verb
    • Object

So:

• Der Verdichter
  • erhöht
    • den Stromverbrauch

That is the most straightforward word order for a simple statement.

Usually, yes, when it means to increase something.

In this sentence, the thing being increased is the direct object:

• den Stromverbrauch

So erhöhen works much like English to increase in sentences such as:

• increase the price
• increase the temperature
• increase the consumption

In German:

• den Preis erhöhen
• die Temperatur erhöhen
• den Stromverbrauch erhöhen

In technical contexts, Verdichter often means compressor, especially in engineering, refrigeration, heat pumps, air systems, or similar fields.

Literally, it comes from the idea of compressing or condensing something. In everyday German, it is not a very common casual word; it sounds technical.

So if you saw this sentence in a manual, product description, or technical explanation, that would be very normal.

Because erhöhen takes a direct object, not an indirect object.

• den Stromverbrauch = accusative
• dem Stromverbrauch = dative

Here, the sentence means that the compressor directly increases the power consumption, so the accusative is needed.

A dative form like dem Stromverbrauch would not fit this verb in this sentence.

A rough English-friendly guide would be:

• erhöht ≈ air-HUHT

A few details:

• the ö is a front rounded vowel that does not exist naturally in standard English
• the h shows that the vowel before the t is long
• the final t is clearly pronounced

So the word is one syllable after the prefix part: er-höht.

If pronunciation is important for you, the trickiest part is the ö sound.
