Questions & Answers about Ich präsentiere den Plan.

Why is it den Plan and not der Plan?

German marks the grammatical function of nouns with different article forms (cases).

• der Plan = nominative (subject)
• den Plan = accusative (direct object)

In Ich präsentiere den Plan:

• Ich = subject (who is doing the action) → nominative
• den Plan = direct object (what is being presented) → accusative

Because Plan is masculine (der Plan), its accusative singular form is den Plan, not der Plan.

How do I know that Plan is masculine?

Unfortunately, in German you usually have to learn the gender together with the noun.

• The dictionary entry will show der Plan (masculine).
• Plural: die Pläne.

There is no 100% reliable rule here; you simply memorize der Plan as a unit. A common tip is to always learn nouns with their article:

• der Plan (m.)
• die Idee (f.)
• das Problem (n.)
