Introduction
To say an action is happening right now, put 在 (zài) in front of the verb: 我在吃饭。(Wǒ zài chī fàn.) — I'm eating. This is the closest Chinese gets to the English "-ing" form, but it marks an action in progress, not a tense — it works equally well for what someone was doing yesterday.
Overview
Structure: Subject + (正) 在 (zhèng zài) + Verb + Object
| Pattern | Example | Translation |
|---|---|---|
| S + 在 + V + O | 我在吃饭。(Wǒ zài chī fàn.) | I'm eating. |
| S + 正在 + V + O | 他正在开会。(Tā zhèngzài kāihuì.) | He's in a meeting right now. |
| S + 在 + V + 呢 | 我在看书呢。(Wǒ zài kàn shū ne.) | I'm reading. |
| S + 没(有) + 在 + V | 我没在睡觉。(Wǒ méi zài shuìjiào.) | I wasn't sleeping. |
| S + 在 + V + O + 吗？ | 你在工作吗？(Nǐ zài gōngzuò ma?) | Are you working? |
在 (zài), 正在 (zhèngzài), 呢 (ne) — how they differ:
- 在 is the plain marker: 我在吃饭。(Wǒ zài chī fàn.)
- 正在 emphasises at this very moment: 我正在吃饭。(Wǒ zhèngzài chī fàn.) — I'm eating right now.
- 呢 at the end adds a relaxed, conversational tone: 我吃饭呢。(Wǒ chī fàn ne.) — 在 can even be dropped when 呢 is there.
- All three can stack: 我正在吃饭呢。(Wǒ zhèngzài chī fàn ne.)

Usage Notes
- 在 here is not the "at a place" 在. Compare 我在吃饭。(Wǒ zài chī fàn.) — I'm eating ／ 我在家吃饭。(Wǒ zài jiā chī fàn.) — I eat at home. If a place follows, it is the location use.
- This is not a tense. 在 works for the past as well: 我昨天在写作业。(Wǒ zuótiān zài xiě zuòyè.) — I was doing homework yesterday.
- The negative is 没(有)在 (méi yǒu zài), not 不在: 我没在工作。(Wǒ méi zài gōngzuò.)
- Adjectives and states cannot take 在. ❌ 我在很高兴。(Wǒ zài hěn gāoxìng.) Only actions can be in progress.
- 呢 (ne) is neutral tone and optional, but it is what makes the sentence sound natural in speech rather than like a textbook.
