Amsterdammertje

An amsterdammertje is a special kind of pole or post you can see in the city of Amsterdam. It's like a small, short traffic pole that usually has three white Xs on it. These poles are placed on the sidewalk or near the edge of the road to protect people and things from cars and bikes. They help make sure that drivers don't accidentally drive onto the sidewalk or bike path, or park their cars in places where they shouldn't be.

The word "amsterdammertje" comes from the name of the city where these poles were first used: Amsterdam. It's a fun word to say, isn't it? You can even try saying it yourself: "amsterdammertje!"

So, whenever you're walking or biking in Amsterdam and you see one of these poles, you know that you're safe from cars and other vehicles because the amsterdammertje is there to protect you!
