鮮明

1. Origins, structure, and basic meaning

• Structure: 鮮明 is read as せんめい and is a な-adjectival noun for an image, color, or memory being distinct and vivid rather than blurred.
• Basic usage: Use 顔が鮮明になる for a change in clarity and 記憶に鮮明に残る for a vivid impression that remains.

2. Common pitfalls and similar expressions

• Visual clarity and memory
  • A restored face becomes visually clear, while the sunset remains vivid as a remembered impression.
• Contrast with 明るい
  • 鮮明 means distinct or vivid; it does not simply mean high in light level or brightness.
