迟到

Using 迟到 is actually pretty straightforward because it usually acts as a verb. You can simply say 我迟到了 (I am late). The 了 at the end indicates that the state of being late has already happened. If you want to specify how late you are, you put the time duration after the word: 我迟到了十分钟 (I was ten minutes late). It is like adding a little salt to the wound of your tardiness. You can also use it as an adjective to describe someone, like a 迟到的学生 (a late student). In the world of apps, if your Didi driver is taking forever, the app might tell you the vehicle is 迟到. If you are texting a friend on WeChat because you are stuck in traffic, you might send a quick 抱歉，我要迟到了 (Sorry, I'm going to be late). It is a very active word. It is not just a state of being; it is a movement that happened behind schedule. Just remember, in Chinese, the 'late' part comes first, then the 'arrive' part. You are 'lately arriving.'

Imagine you are meeting a date at a trendy hotpot spot. You are circling for parking for twenty minutes. You text them: 对不起，堵车了，我会迟到一会儿 (Sorry, there's a traffic jam, I'll be a little late). This is the classic modern usage. Or think about a Zoom call where you are fumbling with your microphone. You join and say: 不好意思，我迟到了 (Sorry, I'm late). In a professional setting, like a job interview, 迟到 is the ultimate villain. You might hear a recruiter say: 他面试迟到了 (He was late for the interview). On social media, you might see a TikToker posting a video of them running to class with the caption: 每天都迟到 (Late every day). It is also used in school settings constantly. Teachers in China are famous for saying: 不准迟到！ (No being late!). Even in the world of online shopping, if a delivery is past its window, you can complain that the package is 迟到. It’s the universal word for the clock winning and you losing.

Use 迟到 whenever there is a specific 'start time' that you have missed. This includes work, school, doctor appointments, movies, weddings, and dinner reservations. It is the perfect word for formal situations because it is precise and clear. If you are a manager and your team is showing up late, you use 迟到 to address the issue. If you are a passenger on a train that is behind schedule, the announcement will use 迟到 (or its formal cousin 晚点). It is also perfect for casual hangouts. If your friend is always the last one to show up to the bubble tea shop, they are the 迟到 king or queen. Basically, if there was an agreed-upon time and the person arrived after that time, 迟到 is your go-to tool. It works across all levels of formality, from a polite apology to a boss to a frustrated text to a sibling. It is the Swiss Army knife of tardiness.

This is where many learners trip up! Do NOT use 迟到 to describe the time of day. If you want to say 'It's late at night,' you cannot use 迟到. In that case, you just use 晚 (wǎn). For example, 已经很晚了 (It is already very late). 迟到 requires an arrival. You also don't use it for things that are just 'slow.' If your internet is slow, it isn't 迟到; it’s 慢 (màn). Don't use it for dead people either—English uses 'the late Mr. Smith,' but in Chinese, that’s a completely different set of words. Also, don't use it if you are just 'late' in starting something but haven't 'arrived' anywhere. If you started your homework late, you wouldn't say you 迟到 your homework. You would say 我晚了 or 我开始晚了. 迟到 needs a destination or an event. If there’s no 'arriving' involved, keep 迟到 in your pocket and reach for 晚 instead. It’s a common mix-up, but once you realize 迟到 needs a 'place' or 'event' to arrive at, it makes sense.

The most frequent error is trying to use 迟到 as a direct translation for the English adjective 'late' in all contexts.

Another mistake is the placement of the time duration. Learners often try to put the time before the verb like in English.

People also forget the 了 (le). Since being late is usually a fact by the time you talk about it, that 了 is your best friend.

Finally, don't confuse 迟到 (chídào) with 知道 (zhīdao - to know). They sound slightly similar to a beginner's ear, but saying 'I know' when you mean 'I'm late' will lead to some very confused faces at the office. Imagine telling your boss 'I know!' when they ask why you're just walking in. Awkward, right?

If you want to sound more like a local, you can use 晚点 (wǎndiǎn). This is very common for flights, trains, and buses. If your flight to Shanghai is delayed, the screen will say 晚点. Another one is 耽误 (dānwu), which means to delay or hold up. You might say 路上耽误了 (I was delayed on the road). For a very informal vibe, you can say 来晚了 (lái wǎn le), which literally means 'came late.' It’s a bit softer than the more official-sounding 迟到. If someone is chronically late, you might call them a 迟到大王 (chídào dàwáng), the 'King of Lateness.' This is a bit tongue-in-cheek and usually reserved for friends who think '7:00 PM' actually means '7:45 PM.' There is also 推迟 (tuīchí), which means to postpone an entire event to a later time. So, if the meeting itself is moved, it’s 推迟, but if YOU show up late to the meeting, you are 迟到.

Beyond the basic verb, you’ll see 迟到者 (chídàozhě) in formal reports or signs, meaning 'one who is late' or 'tardy person.' In school, you might hear about 迟到早退 (chídào zǎotuì), which is the 'sin' of arriving late and leaving early. It’s the ultimate slacker phrase! You might also see 迟到证明 (chídào zhèngmíng), which is a 'late proof' or 'tardy slip'—the bane of every high schooler's existence. In business, some companies have a 迟到罚款 (chídào fákuǎn), a fine for being late. Talk about a motivation to wake up earlier! You can also use it with 'never,' like in the English proverb: 迟到总比不到好 (Better late than never). It’s a direct translation that works perfectly in Chinese too. Whether you’re a 迟到大王 or just someone who occasionally misses the bus, these variations help you navigate the many shades of being behind schedule.

Is 迟到 offensive? No, it’s just a statement of fact. However, if you say it to your boss without an apology, it might come off as rude. Always pair it with a 不好意思 or 对不起. Can I use it for a bus? Yes, but usually people use 晚点 for public transport. However, saying 公车迟到了 is perfectly understandable. Does it always need 了? Not always. If you are saying 'Don't be late,' you say 别迟到 (no 了). But if you are currently late or were late, you need it. Is it used in Taiwan? Yes, it’s standard across the Mandarin-speaking world. In some regions, they might use 底到 in very specific dialects, but 迟到 is the universal winner. Can I use it for a deadline? Not really. For deadlines, you use 逾期 (yúqī) or just say the work is 晚了. 迟到 is for the physical or virtual act of showing up.
