Greetings & goodbyes (Hallo, Guten Tag, Tschüss)

Core phrases

German greetings and goodbyes reflect a clear distinction between formal and informal address, which is central to polite communication. The choice of phrase depends on the time of day and the level of formality, with Sie (formal) versus du (informal) shaping the interaction. Time-based greetings like Guten Morgen are elliptical wishes (short for Ich wünsche Ihnen einen guten Morgen), which explains why the adjective is capitalised and takes the accusative ending -en. Interjections like Hallo and Tschüss are invariant and informal, while Auf Wiedersehen is a formal, prepositional farewell. Understanding this structure helps learners use the phrases correctly without memorising arbitrary rules.

A key usage note: Gute Nacht is only a farewell, never a greeting, and Tschüss is too casual for formal settings. When in doubt, choose the more formal option.

  • Guten Morgen, Frau Müller! – Good morning, Mrs. Müller!
  • Hallo, wie geht's? – Hello, how are you? (informal)

Sie in service situations

In service contexts—shops, restaurants, offices—the formal Sie is the standard, regardless of the setting's casual appearance. This convention maintains respectful distance between staff and customers, and it is reciprocated by customers unless an explicit du offer is made. The verb form with Sie is identical to the third-person plural, but the capitalised pronoun distinguishes formal address from sie (they). Always capitalise Sie and its forms Ihnen and Ihr in writing.

A notable exception: staff may use du with children, but they switch to Sie for accompanying adults.

  • Guten Tag, wie kann ich Ihnen helfen? – Good day, how can I help you?
  • Können Sie mir helfen? – Can you help me?
