空間

1. Origins, structure, and basic meaning

• Structure: 空間 (くうかん) is space available for objects or people. It appears as an area newly created and an existing small area visually altered.
• Basic usage: Moving a shelf opens a broad area by a window; design choices make a cramped room appear brighter.

2. Common pitfalls and similar expressions

• Space physically freed and existing space visually transformed
  • 空間を作る creates usable room, whereas 空間を明るく見せる changes its appearance rather than its dimensions.
