The word "merchandisable" refers to a product or item that is suitable or capable of being sold or marketed. Its antonyms, on the other hand, are words that describe items that are not suitable for sale or marketing. Some antonyms for "merchandisable" include damaged, defective, worthless, unsaleable, unsellable, and nonviable. These words convey the idea that the product is not of good quality, has flaws or issues that render it useless, and cannot be marketed or sold to consumers. It is important for businesses and manufacturers to avoid producing or distributing products that are antonyms of "merchandisable" to maintain their reputations and prevent financial losses.
