väliskuju

Could you clarify what "väliskuju" refers to? I’m not finding a widely recognized concept by that exact term in available sources. Is it a Finnish term, a specific field (linguistics, anthropology, geology, etc.), a brand, or perhaps a fictional concept?

If you’d like, I can:

- write a concise, neutral wiki-style article about "väliskuju" as a real term if you provide a source or context, or

- create a neutral, clearly fictional stub outlining what the concept would entail in a hypothetical discipline, suitable for a wiki entry, with notes indicating it’s fictional.

Let me know which direction you prefer, and any specifics you want included.
