Editing Semantic Drift (section)

=== Current Issues ===

The most common and damaging patterns observed across dictionaries, law, policy, science, and institutional language include:

*'''Silent expansion''' — New cases are continuously folded into an existing definition without creating a Child Instrument or explicit exception, producing overload.
*'''Retrospective continuity claims''' — Later, altered usages are treated as if they were always the meaning of the original term.
*'''Missing boundary work''' — Definitions lack clear “Is Not” exclusions, allowing gradual boundary collapse with related concepts.
*'''Untracked mechanism change''' — The practical tests, decision rules, or causal assumptions attached to a term shift while the surface definition remains stable.
*'''Refusal to fork''' — Classification systems prioritize the appearance of continuity over the creation of cleanly calibrated child instruments, increasing long-term ambiguity.
*'''Orphaned children left unpromoted''' — Specialized usages drift far from their parent concept but are never elevated to independent calibrated status, leaving both parent and child less precise.

These issues are especially consequential in high-impact domains (law, regulation, institutional policy, and technical standards) because uncalibrated semantic drift alters rights, obligations, and outcomes without transparent decision-making.
