Questions & Answers about Der Techniker testet das System im Büro.
Why is Der Techniker used and not Den Techniker?
Because Der Techniker is the subject of the sentence and subjects in German take the nominative case. The masculine nominative article is der, whereas den is the masculine accusative form used for direct objects.
Why is das System and not dem System or den System?
Here das System is the direct object, so it’s in the accusative case. The noun System is neuter, and in singular the neuter article is das in both nominative and accusative. Dem System would be dative, and den System is incorrect because System is neuter (not masculine).
Why does the verb testet appear in the second position?
German main clauses follow the V2 (verb-second) rule: the finite verb must occupy the second position in the sentence. Here the first position is taken by Der Techniker, so testet comes next.
What does im Büro mean, and why not in dem Büro?
im is a contraction of in dem. Since in indicating location (Wo?) requires the dative case, and Büro is neuter, you get in dem Büro, which is commonly contracted to im Büro.
Why are Techniker, System, and Büro all capitalized?
In German, all nouns are always capitalized, regardless of where they appear in a sentence.
Could I use a different verb instead of testet, like prüft?
Yes. prüfen also means “to check” or “to test.” You can say Der Techniker prüft das System im Büro with exactly the same structure and meaning.

“How do German cases work?”
German has four grammatical cases: nominative (subject), accusative (direct object), dative (indirect object), and genitive (possession). The case determines the form of articles and adjectives. For example, "the dog" is "der Hund" as a subject but "den Hund" as a direct object.
