Commercial vs. marchand
In French, both commercial and marchand translate to "commercial" or "relating to commerce" in English, but they are used in different contexts. The word commercial is a broad term relating to the business, corporate, and marketing aspects of trade. On the other hand, marchand is more specific and tangible, closely related to the merchant, the physical goods being sold, or the direct act of buying and selling.
