Rewrite

Rewrite is the process of presenting content in a new form or version, typically by restating words, transforming data, or applying formal rules. It can preserve the original meaning or adapt it for a different audience, purpose, or medium.

In writing and editing, a rewrite substitutes one version of text for another, often to improve clarity, concision, style, or tone. Rewriting may change wording, structure, or emphasis while keeping the core information intact; it may also reframe arguments or translate content for different audiences.

In computer science and linguistics, rewrite refers to rule-based transformation. Term rewriting systems consist of rules that replace subterms with other terms, enabling simplification, normalization, or program transformation. In programming languages, macros or source-to-source compilers perform rewrites to alter syntax or optimize code.

In web development, URL rewriting uses server rules to present clean URLs that map to internal resources. Common tools include Apache's mod_rewrite, Nginx rewrite directives, and the IIS URL Rewrite module. For example, a rule might map /products/12 to /shop/product?id=12.

Across domains, rewriting can improve accessibility, searchability, and consistency, but it also risks changing meaning or introducing errors if rules are imprecise. Good practice includes keeping a clear mapping of original content and verifying rewritten text or rules against the desired intent.
