reversen

Reversen is a term that has no single, universally accepted definition. It is used informally to describe the act or process of reversing or undoing a previous state, arrangement, or operation. In most uses, reversen is treated as a general concept rather than a formal term. The following overview summarizes common interpretations in different contexts.

In mathematics and computer science, reversen can be described as an invertible operation: applying it followed by its reverse yields the original input; the specific inverse operation is context-dependent. In puzzle and game design, a reversen move or reversal refers to a move that returns the game to a prior position or undoes a sequence of actions. In narrative or media studies, reversen can refer to plot reversals that invert expectations, though this is more about technique than a formal term.

The word likely derives from the English "reverse" with the derivational suffix -en, used to form verbs or nouns indicating a process.

Usage notes: Because reversen is not standardized, writers should define the term at first use to avoid ambiguity. When possible, specify the domain, the exact operation, and its inverse.
