redefined

Redefined is the past participle of redefine, meaning that something has had its definition revised or clarified. The term can apply to words, concepts, rules, or symbols. In linguistics, redefinition describes semantic change when a term gains a new sense or shifts its reference, often in response to cultural, technological, or social change. In mathematics and logic, a redefinition updates the definition of a concept, sometimes to resolve inconsistencies or to better fit a theory, with related adjustments to the surrounding framework as needed.

In computer science, redefinition refers to giving a name a new binding. In statically typed languages this can trigger a compile-time error or follow shadowing rules; in dynamically typed languages, names can be rebound to different values. In law and policy, statutory redefinition updates terms to broaden, narrow, or clarify the scope of statutes, regulations, or standards, affecting interpretation and enforcement.

Redefinition can be controversial when it changes long-established meanings, especially in social contexts where terms encode identities or rights. Critics often point to potential confusion or erosion of precision, while supporters argue that redefinition reflects evolving evidence or values and helps maintain relevance. In practice, redefinition is a deliberate act that balances clarity, usefulness, and stability of a language or system.
