着, 过, 在: The Mandarin Aspect Markers That Aren't 了

你在做什么? your friend asks. "What are you doing?" You're halfway into your jacket, one arm through the sleeve, and you answer 我穿着衣服 (wǒ chuānzhe yīfu). Your friend looks puzzled, because you just told them you're already dressed. The sentence you wanted was 我在穿衣服 (wǒ zài chuān yīfu), "I'm putting my clothes on." Both come out in English as "wearing" or "putting on." One little "-ing" does all the work. In Mandarin they're two different pictures, and they take two different markers.

You've probably made peace with 了 by now. Here's the catch: Mandarin has three more aspect markers, and English warns you about none of them. The worst offender is that humble "-ing," which quietly does the job of two separate Mandarin markers at once. This post walks through 在/正在, 着, and 过, then hands you the single question that tells you which of the four markers (these three plus the 了 you know) a sentence actually wants. None of them is tense.

在 / 正在: the action caught in the act

她在看书 (tā zài kàn shū) means "she's reading," right now, book open, eyes on the page. 在 and 正在 sit in front of the verb and mark an action in progress: something unfolding as you speak. 阿姨正在打扫房间 (āyí zhèngzài dǎsǎo fángjiān, "the cleaning lady is cleaning the room right now"). 正在下雨 (zhèngzài xiàyǔ, "it's raining"). This is the closest Mandarin gets to English present continuous.

The split between 在, 正, and 正在 is subtler than most beginners need on day one. Roughly: 在 leans on the status (something is going on), 正 pins the precise moment and usually wants a 着 or 呢 to lean on, and 正在 does both (Written Chinese lays out the three side by side). In everyday speech, plain 在 carries you a long way. Reach for 正在 when you want to stress that it's happening at this very instant.

着: the state the action left behind

Put 他在穿衣服 next to 他穿着衣服 (tā chuānzhe yīfu) and the whole difference shows up. 他在穿衣服 is the action: he's mid-motion, arms going into sleeves. 他穿着衣服 is the state that action left behind: he's dressed, clothes on, nobody's moving. Mango Languages draws the same line with a jacket.

着 sits after the verb and freezes the result in place. 门开着 (mén kāizhe, "the door is open"). 灯亮着 (dēng liàngzhe, "the light is on"). 墙上挂着一幅画 (qiángshàng guàzhe yī fú huà, "a painting hangs on the wall"). The opening, the switching on, the hanging up all happened already. 着 just reports that the result is still sitting there.

Posture verbs live on 着

坐着 (zuòzhe, "sitting"), 站着 (zhànzhe, "standing"), 躺着 (tǎngzhe, "lying down"). 门口站着一位警察 (ménkǒu zhànzhe yī wèi jǐngchá, "a police officer is standing at the door"). These describe the position a body is in, which is a state, not an action you're busy performing. That's why they reach for 着 rather than 在/正在: standing isn't something you're busy doing, it's how you are. So you say 你们坐着，我马上回来 (nǐmen zuòzhe, wǒ mǎshàng huílái, "stay seated, I'll be right back").

着 also glues manner onto a verb

笑着说 (xiàozhe shuō) means "say it with a smile." 着 has a second job: stack it on a first verb and it tells you how the second one happens. 站着说话 (zhànzhe shuōhuà, "talk while standing"). 躺着看手机 (tǎngzhe kàn shǒujī, "scroll lying down"). 孩子哭着对妈妈说 (háizi kūzhe duì māma shuō, "the child said to mom through tears"). English needs a whole "while…" clause to pull this off. Mandarin clips 着 onto the first verb and moves on.

过: the box you've ticked at least once

我去过中国 (wǒ qùguò Zhōngguó) means "I've been to China," at some point, at least once in my life. 过 goes after the verb and marks experience: the thing has happened to you somewhere along the way. 你吃过北京烤鸭吗? (nǐ chīguò Běijīng kǎoyā ma?, "have you ever eaten Beijing roast duck?"). 我学过日语 (wǒ xuéguò Rìyǔ, "I've studied Japanese before").

过 carries a quiet implication: it's over, and often no longer the case. 我去过中国 hints that you aren't in China now (Mango Languages calls this the discontinuity of the event). Negate it with 没, not 不: 我没去过 (wǒ méi qùguò, "I've never been"). If you've worked through 不 vs 没, this is the same 没 doing the same job.

过 vs 了: the experience-versus-trip split

我去过北京 and 我去了北京 both look like "I went to Beijing," and they don't mean the same thing. 我去过北京 (wǒ qùguò Běijīng) is the résumé line: at least once in my life, I've been there. 我去了北京 (wǒ qù le Běijīng) is a specific completed trip, usually one already in play in the conversation ("I went to Beijing, and then…"). GoEast Mandarin frames it as experience versus completion. The 了 you already drilled handles the trip. 过 handles the lifetime tally.

The four-way cue: which marker, which job

Read this sentence: 我坐着喝咖啡，他笑着走过来，问我去过那家新店没有 (wǒ zuòzhe hē kāfēi, tā xiàozhe zǒu guòlái, wèn wǒ qùguò nà jiā xīn diàn méiyǒu, "I was sitting drinking coffee; he walked over smiling and asked whether I'd been to that new shop"). Three markers in one breath. 坐着 is a state (sitting). 笑着 is manner glued onto "walk over." 去过 is experience (have you ever). Add an 在 for an action in progress and a 了 for a completed change, and that's all of Mandarin aspect in miniature.

So when a verb comes up and you're not sure which marker it wants, stop translating and ask what the action is doing in time:

• Unfolding right now, as you speak? → 在/正在. 我在吃饭 (wǒ zài chī fàn, "I'm eating").
• A state that a finished action left lying around? → 着. 门开着 ("the door's open").
• Something you've done at least once in your life? → 过. 我吃过 (wǒ chīguò, "I've had it before").
• A bounded change that just completed? → 了. 我吃了 (wǒ chī le, "I ate, and I'm done now"). The 了 post has the full story.

Notice what's missing from that list: past, present, future. 我在吃饭 could be narrating something that happened at a party last night. Mandarin marks how an action sits in time, not where the calendar puts it. That's the whole reason "-ing" misleads you: English fuses the action and the state into one ending, and Mandarin keeps them on separate shelves.

How to make it stick

The fastest way to wire this in isn't a chart on your wall. It's catching the question hiding behind the sentence. "What are you doing?" wants 在. "What does it look like in there?" wants 着. "Have you ever?" wants 过. Once you hear which question a moment is really asking, the marker stops being a coin flip.

You'll still slip, mostly on the 在/着 split, because English gave you one word for two ideas and old habits run deep. The repair is quick: say it both ways out loud, 他在穿衣服 and 他穿着衣服, and feel which one matches the picture in your head. Do that with a patient speaker (a friend, a tutor, or an AI conversation partner like Conversa that won't tire of the tenth repetition) and the two pictures finally come apart.
