Questions & Answers about Planung macht den Tag ruhiger.

Why is there no article before Planung?

In German, abstract or uncountable nouns used in a general sense often drop the article. Here Planung (planning) is treated as a broad concept—“planning” in general—so no die or eine is needed. If you wanted to talk about a specific plan, you could say Die Planung (the planning) or Eine Planung is possible if you add more context (e.g. Eine gute Planung makes the day calmer), but for the general idea of “planning,” no article is required.

Why is den Tag in the accusative case, and why specifically den?

Den Tag is the direct object of the verb macht (“makes”). In German the direct object takes the accusative. Since Tag is a masculine noun (der Tag in the nominative), its singular accusative form is den Tag.

Why is ruhiger used instead of ruhig?

The form ruhiger is the comparative of ruhig, meaning “more calm.” The sentence says “planning makes the day calmer (than it would be otherwise).” If you used the positive adjective ruhig, you’d simply say “planning makes the day calm,” which lacks the nuance of “more” calm.

Why doesn’t ruhiger have any additional ending, like you’d see with attributive adjectives?

Here ruhiger is a predicative adjective (an object complement) following the verb machen. Predicative adjectives in German do not take case endings—they appear in their base (or comparative) form. If you placed the adjective before a noun (attributively), you would need endings, e.g. ein ruhiger Tag or in comparative attributive use ein ruhigerer Tag.

Could I use eine Planung or die Planung instead of just Planung?

Yes, but with slight changes in nuance:

• Die Planung macht den Tag ruhiger.
  Using die treats “planning” as a known, general process (similar to saying “The planning…” in English).
• Eine Planung macht den Tag ruhiger.
  This is grammatically possible but less common unless you specify what kind of planning (e.g. Eine gute Planung). As a standalone, Eine Planung may feel vague because Planung is normally uncountable/abstract.

Why is the order macht den Tag ruhiger and not macht ruhiger den Tag?

Standard German word order in a main clause is:

1. Subject (or whatever occupies first position)
2. Finite verb (here macht)
3. Object(s) and complements

Within the post-verbal field, direct objects typically come before predicative complements. So den Tag (the direct object) comes before ruhiger (the adjective complement). You could invert them for special emphasis, but the natural, default order is macht den Tag ruhiger.
