What is the German Infinitive? The Foundation of German Verbs

The German infinitive is the basic form of a verb, typically found in dictionaries. It serves as the foundation for all conjugated forms. Most German infinitives end in -en, but some may end in -eln, -ern, or -ein. For example:

• laufen (to run)
• lesen (to read)
• helfen (to help)
• kaufen (to buy)

2. Sie will lesen.
3. Wir müssen helfen.

The Dual Role of the Infinitive: Verb vs. Noun

German infinitives can function as both verbs and nouns, adding complexity to their usage. Understanding this dual role is crucial for accurate communication.

Infinitives as Verbs

When used as verbs, infinitives can form various tenses and moods. For example:

• Ich spiele Fußball. (I play soccer.)
• Sie spielt Fußball. (She plays soccer.)

Infinitives as Nouns

Infinitives can also function as nouns, often referring to actions or concepts. For example:

• Das Schwimmen macht mir Spaß. (Swimming is fun for me.)
