绝缘

• Pinyin: jué yuán
• Hanzi breakdown: 绝 = 纟 (silk) + 色 (colour) — to cut off, sever; 缘 = 纟 (silk) + 彖 (phonetic) — edge, connection

Meaning

To insulate; to be insulated from; to have no contact with; insulation.

Originally a physics term for preventing the conduction of electricity or heat, now widely used figuratively to describe cutting off contact or having nothing to do with something. In technical contexts, refers to electrical insulation (绝缘材料, 绝缘体). In everyday speech, often describes someone deliberately avoiding or being completely disconnected from certain things, people, or situations.
