Etymology
The compound adjective "open-enrollment" is a modern American institutional term. Its first element, "open," derives from Old English, carrying its enduring sense of unrestricted access. The core, "enroll," entered English via French from Latin, where the concept of writing names on a parchment roll (rotula) evolved into formal registration. The suffix "-ment" nominalizes this action. Thus, the term literally describes a "state or process of accessible registration," a concept applied first to educational policies in the mid-20th century and later to health insurance periods, emphasizing low-barrier entry.
