redundant · idle

1. Origins, structure, and basic meaning

• Structure: 冗 can express unnecessary excess or length and has the on-reading じょう.
• Basic usage: 冗談(じょうだん) means a joke, while 冗長(じょうちょう) describes speech or writing that is unnecessarily long.

2. Common pitfalls and similar expressions

• Length versus wordiness
  • 冗長な文章 is not merely a long text but one with excess material, such as repeated content. The expression judges part of the text unnecessary rather than neutrally describing its length.
