unusable

Imagine finding a beautiful antique chair at a flea market, only to discover the legs are completely wobbly and it collapses when you sit on it—that chair is unusable. It means something is in such poor condition or has suffered so much damage that it can no longer serve its intended purpose.

"Unusable" isn't just about physical objects. A plan might be unusable if it's full of flaws, a piece of data could be unusable if it's corrupted, and even an excuse can be unusable if it sounds too flimsy to believe! Think of anything that has reached the point where it simply won't work—that's when you describe it as unusable.

The word "unusable" describes something that cannot be used in a normal, helpful, or intended way. This may happen because it is damaged, defective, incomplete, corrupted, or simply not suitable for the job anymore. For example: "After the flood, much of the furniture was waterlogged and unusable."

"Unusable" can apply to physical items like tools, equipment, furniture, or materials that are broken, worn out, or unsafe to use. But it also extends beyond objects. A strategy might be unusable if it is too flawed to carry out, a document could be unusable if it is illegible or incomplete, and information can become unusable if it is outdated, missing key details, or inaccurate.

The key idea behind "unusable" is that the thing cannot do what you need it to do, at least in its current state. Sometimes that condition is permanent, and sometimes it can be fixed, but right now it is not fit for use. You might say, "The old computer was so slow and glitchy that it became unusable for everyday tasks." Or, "The evidence presented in court was deemed unusable due to improper collection methods."

So, whether referring to a broken appliance, a failed plan, or outdated information, "unusable" suggests that something is not useful in practice and cannot be relied on for its purpose. It is a clear, practical word for something that does not work well enough to be used.
