salable
Able to be sold because people want to buy it.
Salable means able to be sold, or likely to sell well. A salable product is one that customers actually want to buy. A toy company won't manufacture a game unless they believe it's salable. A baker learns which cookies are most salable at her shop and makes more of those flavors.
The word combines two ideas: first, that something can be sold, and second, that it's appealing enough that someone will actually buy it. A brilliant invention that nobody wants isn't very salable. Your old, stained sneakers might technically be possible to sell, but they're probably not very salable.
Writers and artists think about what makes their work salable without sacrificing quality. A musician might write songs they love while also considering whether audiences will want to hear them. Business owners constantly evaluate which products are most salable so they can stock the right items.
When something proves salable, it means you've created something others value enough to exchange their money for it, which is one of the fundamental challenges of business and commerce.
