The process of signing up or registering for something, such as a class or program, and the number of people who have done so.
The enrollment for the new course starts next week.
Enrollment → It is formed from "en-" (meaning to cause to be in) and "roll" (from Old French *rolle*, meaning a list or register) and the suffix "-ment" (meaning the action or result of). The word "enrollment" refers to the action of entering one's name on a list or register, particularly in an educational context.
Think of 'causing to be in' ('en-') a 'list' ('roll') — that's how enrollment means to enter your name on a list.
