inoperable

Imagine a beloved antique clock: its gears are worn, its spring is snapped, and for now it will not tick. We would say the clock is inoperable. The word describes something that cannot work or cannot be used as intended, and it is also very common in medical contexts. A tumor might be inoperable because of its location or size, meaning doctors cannot safely remove it with surgery. But the word is not limited to medicine. An old machine rusting away in a field can also be inoperable. In simple terms, it means something cannot function or cannot be treated with surgery.

The word inoperable often carries a serious tone. At its core, it describes something that cannot work or cannot be used in its present condition. In medical contexts, it has a more specific meaning: it describes a disease, growth, or condition that cannot be treated by surgery. If doctors say a tumor is inoperable, they mean surgery is not a safe or practical option, often because of where the tumor is or how far it has spread.

Outside medicine, the word is used for things that are not working or cannot be put into service. A control panel after a flood, a printer with severe internal damage, or a subway line shut down by a major power failure might all be described as inoperable. In these cases, the idea is usually that the thing cannot operate now. It may later be repaired, replaced, or reopened, but at the moment it is not usable.

That difference matters. In medicine, inoperable usually means "not suitable for surgery." In everyday use, it usually means "not functioning" or "out of service." The word is stronger than simply saying something has a small problem, because it suggests a real barrier to use or action.

So whether you hear it in a hospital room or read it in a report about broken equipment, inoperable points to the same basic idea: something cannot be operated on, or it cannot operate.
