kasheruus

Kasheruus is a neologism used in speculative discussions and some online communities to denote the quality or state by which a proposal, action, or artifact is deemed acceptable within a defined system, community, or set of criteria. It functions as a meta-criterion rather than a substantive attribute of the thing itself, assessing whether it meets the rules that govern judgment in a given context. Because kasheruus has no formal standard definition, its meaning varies with the discourse in which it appears.

The term is described as a portmanteau inspired by the Hebrew kasher, meaning fit or proper for use, combined with a Latin-style suffix -uus to signal a state or property. Its earliest recorded popular usage appears in online forums and speculative writing from the 2020s, but there is no authoritative etymology.

In practice, kasheruus is invoked in discussions of governance, ethics, design, and law to indicate whether a proposal aligns with the accepted criteria for legitimacy within that domain. It is often contrasted with intrinsic merit, focusing instead on whether the system would recognize and approve the merit given its rules.

Examples are hypothetical: a policy proposal might be described as kasheruus if it passes the community’s evidentiary standards, a software feature as kasheruus if it adheres to the project’s contribution guidelines.

Because kasheruus lacks a stable definition, critics argue that it risks circularity or vagueness, reducing transparency about what counts as acceptable. Proponents contend it helps to formalize judgments that would otherwise be ad hoc.
