触る

1. Origins, structure, and basic meaning

• Structure: 触る is read as さわる and is an intransitive verb for touching or handling something with a hand or another part of the body.
• Basic usage: The target appears in 展示品に触る, while a dangerous condition appears in 熱い鍋に触ると危ない; in both, the target is marked with に.

2. Common pitfalls and similar expressions

• Target marker に
  • Rather than を, forms such as 展示品に and 鍋に mark the touched thing with に.
• Negative request
  • A notice asking people not to touch something uses 触らないでください with ないでください.
