The word 课程 is formed by combining two independent characters, each contributing a core idea that merges into a single, more complex concept. 课 originally conveys the idea of a lesson or a subject to be discussed, while 程 suggests a measured process, journey, or program. When placed together, they conceptually "snap into place", with 程 providing a framework of progression or a structured plan, into which the individual 课 or lessons are organized, thus naturally creating the meaning of a "course of study" or "curriculum".
