The word 課題課題 is composed of the kanji 課 (ka), meaning "section," "division," "charge," or "lesson," and 題 (dai), meaning "subject," "topic," or "title." The combination of these two characters suggests a "subject" or "topic" that is "assigned" or "charged" to someone. Therefore, 課題 originally meant "assigned topic" or "assigned subject", but gradually it has come to represent a wider range of meanings such as "task", "problem" and "challenge".
