insä

Could you clarify what you mean by "insä"? It could refer to different things depending on the context, such as a word in Finnish or another language, a personal or place name, or a fictional term. If you specify the intended sense (for example: a linguistic term in Finnish, a place or surname, or a fictional concept), I can draft a concise, neutral wiki-style article (under 300 words). If you’d like a general disambiguation-style article covering multiple possible uses, I can do that as well.
