I asked Duck.ai the meaning of Tüddelkram.

This is what I learned:

"The term "Tüddelkram" is a colloquial expression from Northern Germany, particularly in Low German dialects. It refers to trinkets, knick-knacks, or small, often useless items that clutter a space. The word conveys a sense of affection or mild annoyance towards these little things that accumulate over time. It's often used to describe items that may not have much value but hold sentimental significance or simply take up space."

Even if I don't fully understand the meaning of the word, I will start using it.
