代替

• Pinyin: dài tì
• Hanzi breakdown: 代 = 亻(person) + 弋 (shoot, phonetic); 替 = 夫 (man) + 夫 (man) + 日 (sun) — two people standing ready to swap

Meaning

To replace; to substitute for. Taking the place of someone or something.

Used when one person, thing, or method takes the place of another. Can describe temporary substitution (filling in for someone) or permanent replacement. Distinguished from 替代 which is more formal and emphasises a complete replacement. Common in both everyday and formal contexts.
