The answer to the puzzle is vijver.
A vijver is a Dutch word for a small lake or pond. It is typically a shallow body of water with a surface area of less than 10 hectares (25 acres). Vijvers are often found in rural areas and are used for a variety of purposes, including fishing, swimming, and irrigation.
The word “vijver” is derived from the Old Dutch word “wīver”, which means “pond”. The word is also related to the German word “Weiher” and the English word “weir”.
Vijvers are an important part of the Dutch landscape. They provide habitat for a variety of plants and animals, and they also help to regulate the water flow in rivers and streams.
