Here are some possibilities depending on what you're looking for:
* "Paño" means "cloth" or "rag".
* "Pan" means "bread".
* "Plano" means "flat" or "map".
* "Pano" might be a misspelling of "pano", a slang term in some Spanish-speaking countries for "guy" or "dude".
Could you please provide more context about what you're looking for? For example, what is the sentence where you saw "panos"?
