Modal Verb Sentence Structure

Modal verbs in German follow a specific sentence structure: Formula: Subject + Modal Verb + ... + Infinitive Verb (at the end) The infinitive verb goes to the end of the sentence in main clauses. This is a key feature of German word order. Negation: "nicht" usually comes before the infinitive verb. Questions: The modal verb moves to the first position.

Examples

Ich kann heute nicht kommen.
I can't come today. (negation before infinitive)
Kannst du morgen arbeiten?
Can you work tomorrow? (modal verb first in question)
Wir müssen um 8 Uhr in der Schule sein.
We have to be at school at 8 o'clock. (infinitive at end)

Common Modal Verb Combinations

Certain modal verbs are frequently used together or in specific contexts: Double modals: Sometimes two modal verbs appear together Fixed expressions: Some phrases always use specific modal verbs Polite forms: Certain modals are preferred for politeness Learning these combinations will make your German sound more natural.

Examples

Ich möchte gerne kommen.
I would like to come. (polite form with gerne)
Du solltest das nicht tun.
You shouldn't do that. (sollten = conditional of sollen)
Könnte ich bitte...?
