ytti

Could you specify what you want to cover with "ytti"? The term can refer to multiple things (for example a Finnish word or name, a person or organization, a software or project acronym, etc.). If you have a particular context in mind, I can write a concise, neutral wiki-style article focused on that interpretation, under 300 words. If you’d like, I can also provide a general disambiguation-style entry covering the main uses.
