About
The character 课, composed of the semantic component 言 (speech) and the phonetic component 果 (fruit, result), originally carried a meaning centered around testing, assessment, and investigation, conceptually linking the act of verbal inquiry to a resultant judgment. Over centuries, its application shifted from the process of examination itself to denote the subject matter being examined or studied, thereby evolving to mean a lesson, a course of study, or a defined branch of academic learning. This semantic expansion reflects a natural progression from the act of evaluating knowledge to the structured content that is evaluated, solidifying its primary modern sense as a standard unit of teaching.
