püsivamates

I’m not aware of a widely recognized concept or topic named “püsivamates.” To write an accurate wiki-style article, I’d need some context or clarification about the term. Could you specify the intended meaning, language, or field? For example:

- Is it an Estonian term related to people (such as permanent residents) or to a linguistic concept?

- Is it the name of a place, a organization, or a theoretical idea in a specific discipline?

- Do you want a neutral stub article documenting the term itself (definition, usage, etymology) or a broader article about a concept it represents?

If you can provide a hint about the intended meaning, I can produce a concise, neutral wiki-style article under 300 words.
