A useful related word is 替代, which also means “to replace” or “to substitute.” In many contexts, 代替 and 替代 are similar, but 代替 is often more common in everyday speech when talking about one person or thing taking the place of another. 替代 may sound slightly more formal or technical, especially in phrases like 替代能源, meaning “alternative energy.”

Another related expression is 替……做, meaning “to do something for someone.” For example, 我替你去 means “I’ll go for you” or “I’ll go in your place.” This is related in meaning, but 代替 is more directly about replacement or substitution.

Conclusion

代替 means “to replace,” “to substitute for,” or “to take the place of.” Remember the structure A 代替 B: A takes the place of B. It is useful for talking about people, machines, methods, or objects that perform the role of something or someone else.
