tvirt

Could you provide more context for the term “tvirt”? Is it a real-world term from a specific language or field, an acronym or brand, or a fictional/conceptual term? Do you want a factual encyclopedic entry about a real term, or a neutral, fictional wiki-style article for a constructed concept? If you specify the intended meaning and domain (linguistics, technology, culture, etc.), I can craft a concise, neutral article under 300 words.
