Start with the intended meaning
Identify the noun phrase being described before choosing the apposition’s ending. In the article-marked patterns here, case agreement is visible. A middle insertion needs a closing boundary as well as an opening one.
Attach the apposition and close the insertion
Ich spreche mit Frau Berger, der Leiterin des Teams, über den Termin. Mit requires dative, and the article-marked apposition der Leiterin agrees in dative with Frau Berger. With für, the apposition becomes die Leiterin. The pair of commas encloses the additional description. A bare occupational label can behave differently: Frau Berger, Leiterin des Teams, … does not show the same article-marked case pattern. Do not condemn every uninflected-looking title as wrong.
Die Entscheidung – das betonte Lea ausdrücklich – gilt nur für diesen Monat. Both dashes mark the parenthesis; the main sentence still reads Die Entscheidung gilt nur für diesen Monat. If you use commas or brackets for another insertion, keep the matching boundaries and the main clause’s structure. An inserted clause can carry an important qualification. Removing it for a reading test is different from deleting its meaning in a final rewrite.
Apply the pattern in another context
Ich helfe Nora, einer neuen Kollegin.
Helfen requires dative; einer neuen Kollegin describes Nora in dative.
Wir sprechen über Tuan, den neuen Trainer.
In this about construction, the apposition den neuen Trainer matches the accusative reference.
Choose the form and explain the meaning
7. Complete: “mit Frau Berger, ___ Leiterin des Teams, …”
der. The article-marked apposition agrees with the dative expression after mit.
Additional check 1. Complete: bei Lara, ___ Leiterin des Vereins, …
Der. Bei selects dative, and the article-marked feminine apposition follows that case in this pattern.
Additional check 2. Add both commas: Tuan der Kursleiter wartet im Hof. Intended: der Kursleiter is an inserted description.
Tuan, der Kursleiter, wartet im Hof. The second comma closes the inserted description before the main clause continues.
Additional check 3. Is every bare occupational label automatically wrong because it has no article-marked ending?
No. Bare labels can behave differently. Check the actual construction instead of extending the article-marked example to every title.
