The phenomenon you're referring to is called "verb-final" or "verb-at-the-end" word order in German. It is indeed a distinctive feature of German grammar compared to languages like English and Spanish, which typically follow a subject-verb-object (SVO) word order.

The verb-final word order in German is a result of its rich system of grammatical cases and complex sentence structures. Here are a few factors that contribute to this word order:

Verb Position in Subordinate Clauses: In German, subordinate clauses often provide additional information or express complex relationships within a sentence. In these clauses, the conjugated verb is typically placed at the end, following all other sentence elements. This is known as the "subordinating conjunction" rule.

Verb Placement with Modal Verbs: German frequently uses modal verbs such as "können" (can), "müssen" (must), or "wollen" (want to). When a modal verb is used, the main verb (infinitive) is placed at the end of the clause or sentence. For example, "Ich kann Deutsch sprechen" (I can speak German).

Verb Placement in Questions: In interrogative sentences, the finite verb is typically placed at the beginning of the sentence, and the subject follows. However, in certain complex questions or subordinate clauses, the verb can appear at the end. For instance, "Wissen Sie, wann er kommt?" (Do you know when he is coming?).

The verb-final word order in German can seem unusual to speakers of languages that follow different word orders. However, it is important to note that word order is just one aspect of a language's grammar, and each language has its own unique structure and rules. Linguistically, the reasons for these differences often lie in historical development, cultural factors, and the evolution of the language over time.

It's also worth mentioning that not all German sentences have a verb at the end. In main clauses and simple sentences, the verb typically appears in the second position, following the initial element. It is in more complex sentence structures and subordinate clauses where the verb-final order becomes more prominent.

Overall, the verb-final word order in German is a characteristic feature of its grammar, and understanding its rules and usage contributes to fluency and comprehension in the language.
