The word for “idiot” in German is “Idiot.” It’s pronounced similarly to English, though the emphasis may vary slightly depending on the speaker’s accent.
In casual conversations, you might also hear some other words that convey a similar meaning, such as “Dussel” or “Trottel.” Both of these terms can refer to someone who is silly or foolish, often in a more lighthearted or humorous context.
It’s worth noting that language can be nuanced, and while these terms are commonly used, their connotations might vary by situation, so it’s always good to be mindful of context when using them.
