科目

1. Origins, structure, and basic meaning

• Structure: 科目 is read as かもく and is a noun for a subject or course defined within a school or educational curriculum.
• Basic usage: Use 科目を履修する for formally taking a course and 好きな科目は歴史だ for identifying a favorite subject.

2. Common pitfalls and similar expressions

• Subject versus topic
  • 科目 is a curricular subject, not merely a discussion or research topic such as テーマ.
