Weil vs Denn – Because vs For/Because

In German, weil and denn both explain reasons, but they differ in grammar and emphasis. This short guide shows when to use each so your explanations sound natural.

Weil

Use weil to give a cause with a subordinate clause; the verb goes to the end and the listener focuses on the reason. Weil is common in speech and writing when you want to connect smoothly to the cause.

Denn

Use denn to give a reason in a main clause; it preserves the normal word order and feels less formal than weil. Denn works well when you add a quick explanation or when you reply to a question.

Summary

Use weil for subordinate clauses where the verb goes to the end and the reason is part of a larger sentence. Use denn to add reasons in main clauses that keep normal word order and sound more like a quick explanation.
