The Origin of the term Slug

The origin of the term “slug” in the context of URLs has its roots in the traditional newspaper publishing industry.

In the days of typesetting and physical layouts, a “slug” was a short, often single-word headline or identifier used to label a story as it moved through the editing and printing process.

Similar to a newspaper slug briefly summarizing a story, a URL slug acts as a condensed, descriptive identifier for a specific web page. This analogy led to the adoption of the term in web development.
