Everyone makes mistakes, especially when you start learning Chinese. Learn how to use the result complement 错 (cuò) to express making mistakes!

Structure
To express that an action resulted in an error, you can use a result complement with -错. This covers what is often expressed with the adverb "incorrectly" in English.
Note that this sentence puts the object first as a topic.

Examples

Zhè ɡè zì nǐ xiě cuò le.
这 个 字 你 写 错 了。
You wrote this character wrong.

As with all result complements, the -错 result complement works particularly well in a 把 sentence.
