替代

• 拼音: tì dài
• 汉字拆解: 替 = 夫 (man) above 日 (sun) — historical form suggesting one person standing in for another; 代 = 亻(person radical) + 弋 (shoot/stake, phonetic component)

含义

To replace; to substitute; to take the place of. One thing or person assuming the role or function of another.

Used in both concrete (replacing a product or material) and abstract (replacing a concept or position) contexts. More formal than 代替, though the two are often interchangeable. Frequently used in science, technology, and social commentary to describe substitution.
