重要

1. Origins, structure, and basic meaning

• Structure: 重要 is read じゅうよう and means having substantial weight in a judgment or action.
• Basic usage: It describes documents needing careful storage or a process that matters in a discussion.

2. Common pitfalls and similar expressions

• Modifying a noun or making a statement
  • In 重要な書類, な links the word to a noun. In 過程も重要だ, it states at the end of the sentence that the process matters too.
• Focus compared with 大切
  • 大切 can express cherishing something or treating it carefully. 重要 tends to emphasize its significance for a purpose or outcome; both can apply to documents or processes.
