semestrid

I can’t locate a widely recognized concept or term named "semestrid" in standard reference materials. Without reliable sources, I can’t produce a factual encyclopedia article. Could you provide context, field, or a source for the term? For example, is it a scientific term (biology, geology, astronomy), a linguistic or cultural concept, or perhaps a misspelling of another word (such as “semistrid,” “semestral,” or similar)?

If you intended a fictional or hypothetical term, I can draft a neutral, wiki-style stub clearly labeled as fictional and structured with definitions, characteristics, history or usage, and references. Please share any preferred scope, audience, or details, and I’ll craft a concise article under 300 words.
