Questions & Answers about Ich öffne den Kalender und mache eine Notiz.
Why is den Kalender used instead of der Kalender?
Because den Kalender is the masculine singular direct object of the verb öffnen, which requires the accusative case. In German, the definite article for masculine nouns changes from der (nominative) to den (accusative).
Why is eine Notiz used instead of einen Notiz or ein Notiz?
The noun Notiz is feminine in German. The indefinite article for feminine nouns in both nominative and accusative is eine. Einen would be for masculine accusative, and ein for neuter.
Why is the subject ich omitted in the second clause und mache eine Notiz?
When two main clauses are joined by a coordinating conjunction like und, and both share the same subject, you can omit the repeated subject in the second clause. The verb still occupies the second position: und + mache + eine Notiz.
Why does machen eine Notiz mean “to make a note”? Can I use schreiben instead?
