purveyor
This term carries a sophisticated, often formal tone, suggesting a level of curation or specialized expertise. When used for goods, it implies a high-quality source rather than a generic retailer, often evoking images of traditional tradesmen or luxury suppliers.
In a social or intellectual context, the word takes on a more critical or skeptical edge. Describing someone as a purveyor of rumors or lies suggests a deliberate, systematic distribution of misinformation, framing the person as a merchant of falsehoods.
