JLPT N3

Character Breakdown

Meaning and Usage

"説" (せつ) primarily means "theory" or "explanation." It is often used in academic, scientific, or intellectual contexts to refer to a proposed idea or interpretation that explains a phenomenon.

Common Collocations

  • "説を唱える" (せつをとなえる): to advocate or propose a theory.
  • "説得力" (せっとくりょく): persuasive power or convincing force.
  • "新説" (しんせつ): a new theory or hypothesis.

Usage Notes

When using "説," speakers often imply a certain level of reasoning or evidence behind the idea, but it may not be fully proven. It is common in discussions where multiple theories or viewpoints exist.

Common Mistakes

Learners sometimes confuse "説" with "話" (はなし), which means "story" or "talk." Remember that "説" is more formal and intellectual, focusing on theories or explanations rather than casual stories.
