副題

1. Origins, structure, and basic meaning

• Structure: 副題 is read as ふくだい and means “subtitle”.
• Basic usage: It refers to placing a subtitle on a cover and shortening an overly long subtitle.

2. Common pitfalls and similar expressions

• Key distinction: 作品の副題
  • It is a title supplementing the main title, so 作品の副題 presupposes the work’s primary title.
