kätköisiä

Kätköisiä is a Finnish word that translates to "hidden" or "concealed" in English. It is most commonly used in the context of geocaching, a popular outdoor recreational activity. In geocaching, a kätkö is a hidden container, often called a cache, that participants seek out using GPS coordinates. The term is an integral part of the geocaching community in Finland.

When referring to a kätkö, it implies that the object is deliberately placed out of sight, requiring effort and navigation to find. This could be a small waterproof box, a magnetic container, or any other object designed to be hidden in a natural or urban environment. The act of searching for a kätkö is known as "kätköily," which translates to geocaching itself. Participants often leave small trinkets or logbooks inside the kätkö for others to discover and sign. The discovery of a kätkö is typically met with satisfaction and a sense of accomplishment. The word "kätköisiä" can also be used more broadly in everyday language to describe anything that is hidden, secret, or not readily apparent.
