Character Breakdown

Meaning and Usage

The word "解説" (かいせつ) means "explanation" or "commentary." It is commonly used when someone clarifies or elaborates on a topic, often to make something easier to understand. It can refer to written or spoken explanations.

Common Contexts

You will often see "解説" in educational materials, news programs, and books where difficult concepts or events are explained. For example, teachers provide 解説 to help students understand problems, or experts give 解説 during broadcasts.

Collocations and Patterns

  • 解説する: to explain or commentate
  • 解説を聞く: to listen to an explanation
  • 解説付き: with commentary or explanation

These phrases are useful when discussing explanations in various contexts.

Register and Nuance

"解説" is a neutral and formal word, suitable for academic, professional, and media contexts. It is not casual, so it is less common in everyday informal conversation.

Common Mistakes

Learners sometimes confuse "解説" with "説明" (せつめい), which also means "explanation." While both can be used similarly, "解説" often implies a more detailed or expert commentary, whereas "説明" is more general. Use "解説" when emphasizing detailed or analytical explanation.
