tenuus

Could you clarify what you mean by "tenuus"? It is not a widely recognized term, and there are multiple possible interpretations (for example, a misspelling of another word, a Latin-origin term, or a fictional/conceptual name). Do you want:

- a real-world, concise stub about an obscure linguistic or historical usage,

- a fictional or hypothetical concept with a neutral encyclopedic description, or

- a clarification note about possible meanings and etymology?

Once you specify the context, I’ll draft a concise, neutral wiki-style article under 300 words.
