Etymology: "Preenroll" is "pre-" attached to "enroll," so its story is mostly a matter of how the two parts came together. "Enroll" comes from Old French "enrouler," meaning to put on a roll or list, and the English form entered through Anglo-Norman and Middle English, with the "en-" prefix and the sense of entering a name in a register. The Latin root "rotulus," meaning a small roll, sits behind that French verb. The prefix "pre-" comes from Latin "praeter" or "prae," meaning "before," and it was productive in English for forming compounds that mean "in advance of" the base action. Speakers simply attached it to "enroll" to describe registering before a formal enrollment period opens, a use that became common as schools, universities, and insurance plans began advertising early sign-up windows. The compound is a modern formation, so it has no history older than its parts.
