The kanji 題 conveys the idea of a “title” or “theme” — whether for a work, a question, or a subject of discussion. It is frequent in school-related terms such as 宿題 (homework) and 問題 (problems).

Its radical 頁 (おおがい, “head/page”) often indicates ideas linked to headings, pages, or matters to think about.
