Grammar Focus: Similar Chinese Adverbs
Many Chinese learners translate 暗暗, 悄悄, and 偷偷 as “secretly.”
They are similar, but they are not exactly the same.
The key difference is:
暗暗 = secretly in one’s heart / without showing one’s feelings
悄悄 = quietly / without making noise or attracting attention
偷偷 = secretly / without letting others know, often because you do not want to be discovered
Let’s look at them one by one. 🌿
1. 暗暗(àn’àn)
Secretly in one’s heart / silently inside

2. 悄悄(qiāoqiāo)

It mainly means the action is quiet, careful, or not easy to notice.
3. 偷偷(tōutōu)
Secretly / without being discovered
偷偷 focuses on hiding an action from others.
Sometimes the action may be against rules, not allowed, or something the speaker does not want others to know.
However, 偷偷 is not always negative. It can also be used for surprises.
