Der Anschlussverlust verändert den Reiseverlauf.

Because Anschlussverlust is the subject of the sentence, and Reiseverlauf is the direct object.

• der = masculine nominative article
• den = masculine accusative article

So the sentence structure is:

• Der Anschlussverlust = the missed connection / connection loss (subject)
• verändert = changes
• den Reiseverlauf = the course of the journey / itinerary (object)

This article change is very important in German because it helps show who is doing the action and what is being affected.

The noun Anschlussverlust is a compound noun, and in German the last part of a compound usually determines the gender.

• der Verlust = loss
• therefore der Anschlussverlust = missed connection / connection loss

So even though the first part is Anschluss, the gender comes from Verlust, which is masculine.

For the same reason: the final part determines the gender.

• der Verlauf = course, progression
• therefore der Reiseverlauf = course of the journey / travel progression

That is why:

• nominative: der Reiseverlauf
• accusative: den Reiseverlauf

It is a compound made of:

• Anschluss = connection, especially a transport connection
• Verlust = loss

So literally it means connection loss. In travel context, it usually refers to missing a connection or the loss of a connecting connection.

A native English speaker might naturally think of a missed connection.

It is also a compound:

• Reise = journey, trip, travel
• Verlauf = course, progression, development

So Reiseverlauf literally means the course of the journey or how the trip proceeds.

Depending on context, English translations could include:

• itinerary
• travel plan
• course of the trip

Verändert is the 3rd person singular present tense form of verändern.

The subject is singular:

• der Anschlussverlust = singular

So the verb must also be singular:

• ich verändere
• du veränderst
• er/sie/es verändert

That is why the sentence uses verändert.

Because German main clauses usually follow the verb-second rule, often called V2.

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

• Der Anschlussverlust | verändert | den Reiseverlauf

Here:

1. first position = Der Anschlussverlust
2. second position = verändert

This is one of the most important German word-order rules.

Yes. German allows different word orders for emphasis, as long as the verb stays in second position in a main clause.

For example:

• Den Reiseverlauf verändert der Anschlussverlust.

This still means the same thing because the articles show the grammatical roles:

• den Reiseverlauf = object
• der Anschlussverlust = subject

This version sounds more marked or emphatic, because it puts emphasis on den Reiseverlauf.

German very often forms compound nouns by writing them as one word.

So instead of something like:

• Anschluss Verlust
• Reise Verlauf

German writes:

• Anschlussverlust
• Reiseverlauf

This is completely normal in German. English often prefers separate words, but German often combines them into one noun.

Because all nouns are capitalized in German.

So in this sentence:

• Anschlussverlust = noun
• Reiseverlauf = noun

That is why they begin with capital letters, even in the middle of the sentence.

They are related and can overlap, but verändern often means to alter or to change something in a noticeable way, while ändern can be a bit more general, like to change or to modify.

In this sentence, verändert den Reiseverlauf sounds very natural: the missed connection alters or changes how the trip proceeds.

So:

• ändern = change
• verändern = change/alter, often with a stronger sense of affecting the overall state or course

Yes. German often uses the present tense in cases where English might also use the present tense.

So verändert simply means changes. It describes a general fact or current effect:

• the missed connection changes the course of the trip

If you wanted to put it in the past, German would use a past form, for example:

• Der Anschlussverlust veränderte den Reiseverlauf.
• Der Anschlussverlust hat den Reiseverlauf verändert.

A rough pronunciation guide is:

dehr AHN-shloos-fehr-LOOST fer-EN-dert den RY-zeh-fer-lowf

A few helpful points:

• Anschluss has the sch sound like sh
• eu does not appear here, but ei in Reise sounds like English eye
• v in verändert is pronounced like f
• w in German usually sounds like English v, but there is no w in this sentence

If you want a more natural rhythm, stress these parts:

• der Anschlussverlust
• verändert
• den Reiseverlauf

It is understandable and quite natural in formal or transport-related contexts, but in everyday speech Germans might often say something more direct, such as:

• den Anschluss verpassen = to miss the connection
• das Verpassen des Anschlusses = missing the connection

So this sentence is grammatically normal, but it may sound a bit more formal or technical than very casual everyday speech.
