What is the condition of being separated or cut off from something?

The condition of being separated or cut off from something is best described by the term "severance." This word specifically denotes the act of breaking or disconnection from a relationship, association, or situation, making it fitting for the definition provided in the question. In contexts such as employment, a severance can refer to the termination of an employee’s contract and the subsequent disconnection from the workplace. This term emphasizes a clear division or cut from what was previously connected.

The other terms do not align with this definition. "Satire" refers to a literary or artistic form that critiques or mocks human vice or folly. "Squander" means to waste something, typically resources or opportunities, indiscriminately. "Sanction" often relates to a penalty or a measure taken to enforce compliance or disapproval. None of these terms encapsulate the idea of separation or disconnection as effectively as "severance."
