uurtumiset
Could you clarify what you mean by "uurtumiset"? Is it a real Finnish term referring to a specific concept (for example, a timekeeping practice, a cultural phenomenon, or a historical event), or would you like me to create a fictional, encyclopedia-style article about a concept by that name? If you prefer, I can proceed with a concise, neutral entry defined as a real term or as a fictional concept, but I’ll need to know which direction you want.
