Questions & Answers about Die Leute in der Gemeinschaft kennen einander.
Could I use sich instead of einander in this sentence?
Yes, you absolutely could say Die Leute in der Gemeinschaft kennen sich. In German, the plural reflexive pronoun sich is often used to mean 'each other'. However, einander is purely reciprocal. Using einander makes it impossible to misunderstand the sentence as 'they know themselves'.
Why is it in der Gemeinschaft (dative) rather than in die Gemeinschaft (accusative)?
in is a two-way preposition. Because this sentence describes a static location where the people already are—rather than a movement towards a new destination—we use the dative case. Gemeinschaft is a feminine noun, so die changes to der in the dative.
Why is the verb kennen used here for 'know' instead of wissen?
You use kennen when you are familiar with a person, place, or thing. wissen is strictly used for knowing facts or specific pieces of information. Since the sentence is about being acquainted with other people, kennen is the right choice.
What is the difference between using Leute and Menschen for 'people'?
