spiiri

Could you clarify what you mean by "spiiri"? It is not a widely known term in English, Finnish, or other major languages, so I want to ensure I write a correct, neutral wiki-style article. Please specify:

- The intended meaning or context (e.g., a place, organization, concept, product, person, or a fictional term).

- Any regional or language focus (e.g., Finnish, Estonian, fictional universe).

- The desired scope (historical overview, current status, notable examples, pronunciation, etymology).

Once you provide the context, I’ll draft a concise, neutral article under 300 words.
