語る

1. Origins, structure, and basic meaning

• Structure: 語る(かたる) is a transitive verb for telling or discussing an experience, idea, or appeal in one's own words.
• Basic usage: A topic appears in 旅について語る, while a directly described subject appears in 作品の魅力を語る.

2. Common pitfalls and similar expressions

• Topic and object
  • Use について to introduce a topic and を for the content addressed directly.
