矢印

1. Origins, structure, and basic meaning

• Structure: 矢印 (やじるし) is an arrow symbol showing direction or location. 矢印に沿って guides movement; 矢印を書く creates the mark.
• Basic usage: A floor arrow leads toward an exit, while a red arrow is drawn on a map to indicate a destination.

2. Common pitfalls and similar expressions

• Directional mark followed and location mark drawn
  • With に沿って, an existing sign guides a route; with を書く, the sign itself is newly produced. The word refers to a symbol, not a physical arrow projectile.
