"Unviable" Natural Recordings by Native Speakers
Unviable means not capable of being made successful or profitable; not practical or feasible.
Example: "The company's current business plan is unviable due to market conditions."
Somewhat hidden or concealed, but now revealed or disclosed publicly, often because it was deliberately kept secret or hidden.
