Chinese verbs are not just about actions; they also show how verbs can express results, completion, and capability. In this article, we’ll explore three common complements: 懂 dǒng, 完 wán, and 了 liǎo, and see how these small words can completely change the meaning of a sentence.

懂 dǒng – to understand / comprehend

OneDotDot Chinese

Whenever I ask foreigners, "Do you speak Chinese?" they often reply, "a little bit" (yì diǎn diǎn). That inspired me to create this website and translate "yì diǎn diǎn" into the quirky and fun "One Dot Dot."

It’s also a reminder that learning Chinese is a journey, and progress happens one step at a time. By learning just a little bit every day, you’ll go far!
