perpetuity

Imagine setting something up so it never has to stop. That is the basic idea here. It means lasting forever, or for an unlimited length of time. You will often see it in the phrase "in perpetuity," especially when talking about money, property, rights, or support that is meant to continue without an end date.

For example, a donation might support a school in perpetuity, or a legal agreement might grant someone rights in perpetuity. The word is common in legal and financial writing, where people want to stress that something is meant to last forever.

Perpetuity describes something that continues forever, with no fixed end. It points to an endless stretch of time, often reaching far beyond a single lifetime. In everyday speech, people do not use it very often, but it becomes important when talking about things meant to last for generations, such as legacies, traditions, rights, trusts, or long-term agreements.

You will most often meet the word in the phrase "in perpetuity." A trust may be established in perpetuity, meaning it is supposed to keep going indefinitely. A fund might provide yearly support in perpetuity. A contract might grant the use of a name, image, or piece of land in perpetuity. In all of these cases, the idea is the same: there is no planned finish.

The word comes from the Latin perpetuus, meaning "continuous" or "without stopping." Because of that, it often appears in formal, legal, and financial language. Still, it can also be used in a broader way when people talk about traditions, memory, or values that seem as if they will endure forever.

In real life, of course, very few things truly last forever. Laws change, institutions close, and customs fade. Even so, the word expresses the intention or promise of something continuing without limit. When you see it, think of something meant to keep going year after year, with no end in sight.
