خسته نباشی

Using this phrase is like knowing a secret handshake. You can use it as a greeting, a goodbye, or a 'thank you.' If you walk into a dry cleaner and they are busy ironing, start with خسته نباشی. It replaces salam in that specific context. If you are leaving a long meeting, say it to your colleagues as you walk out. It functions as a polite 'good job' and 'goodbye' wrapped into one. On social media, you’ll see it in comments under a friend’s workout video or a long thread about a coding project. It’s perfect for the person who just delivered your food through a Snapp app. A quick خسته نباشید (the formal version) as you take the pizza makes the driver feel seen. Don't overthink the grammar. Just drop it whenever you see someone in the middle of a task or just finishing one. It’s a low-risk, high-reward expression. Just remember to smile. A grumpy خسته نباشی sounds like you’re complaining they aren’t tired enough!

Like most Persian expressions, formality depends on who you are talking to. If you are chatting with your best friend after they studied all night, use خسته نباشی. It’s casual and intimate. If you are talking to your professor, a taxi driver, or someone older, use خسته نباشید (khaste nabashid). The id at the end adds that necessary layer of Persian politeness (Taarof). There is also a middle ground: خسته نباشین (khaste nabashin). This is the 'cool' formal version often used in modern Tehran. It’s polite but less stiff than the full id ending. Think of it like the difference between 'Hey man' and 'Good afternoon, sir.' If you aren't sure, always go with the formal خسته نباشید. Iranians will never be offended by extra politeness. They might even give you a discount on those saffron pistachios! Using the wrong register isn't a disaster, but using the formal one with a shopkeeper shows you’ve really done your homework.

Imagine you’re in a Snapp (the Iranian Uber). The driver has been in traffic for two hours. As you get out, say دستتون درد نکنه، خسته نباشید. You’ve just made his day. Or maybe you’re watching a Twitch streamer who just finished an 8-hour marathon. Typing خسته نباشی in the chat is the standard move. In a professional Zoom call, as the host ends the meeting, you’ll hear a chorus of خسته نباشید. It’s the polite way to sign off. Even in gaming, if your teammate carried the whole match, a quick خسته نباشی in the chat is the highest praise. It’s also used sarcastically! If your brother finally wakes up at 2 PM, you can say خسته نباشی! with a smirk. It’s like saying 'Wow, you must be exhausted from all that sleeping.' This sarcastic edge is very common among Gen Z and Millennials. Use it sparingly, or you might end up doing the dishes yourself.

You should use this whenever you witness effort. See a waiter carrying a heavy tray? Say it. See a friend finishing a difficult workout? Say it. It’s perfect for the end of a class to thank your teacher. It’s great for the person behind the counter at the bank. It is especially powerful when someone has done something for *you*. While mamnoon means thanks, adding khaste nabashi adds a layer of empathy. It says 'I know this was work for you.' Use it when you see a janitor cleaning the hallway. Use it when you see a street performer packing up. It is the language of the working class and the professional class alike. It’s a universal sign of respect. Basically, if someone is doing anything other than sitting on a couch eating grapes, they probably deserve a خسته نباشی.

There are a few places where this phrase feels weird. Don't say it at a funeral; it’s not the time to focus on 'tiredness.' Don't say it to someone who is clearly having a blast and not working, like a kid on a swing. They aren't 'khaste' and they don't want to be reminded of work. Also, avoid saying it to someone who has just woken up—unless you’re being sarcastic. If you say it to someone who is grieving, it might come off as trivializing their pain. It’s a phrase for *action*, not for *stasis*. Also, don't say it to a bride and groom during their wedding ceremony. They are busy, yes, but calling them 'tired' is a bit of a mood killer. Stick to mobarak bashe (congratulations) there. If you say it to someone who is literally doing nothing, they might look at you like you’ve lost your mind. It’s like trying to charge a battery that’s already full.

The most common mistake is treating it like a noun. You can't say 'Thanks for the khaste nabashi.' It’s an action! Another mistake is using the casual version with your boss. Unless your boss is your literal cousin, stick to the plural nabashid. Some learners try to translate 'Good job' literally as kar-e khoob. While that works, it sounds like a Google Translate robot. خسته نباشی is what a human would actually say.

Also, don't confuse it with khabam miad (I’m sleepy). Being 'khaste' is about energy depletion from work, not just wanting to go to bed. If you tell a waiter khabam miad instead of khaste nabashi, they might point you to the nearest hotel instead of bringing the check.

You will hear a few versions of this. The most formal is خسته نباشید (khaste nabashid). The casual is خسته نباشی (khaste nabashi). In Tehran, you’ll hear خسته نباشین (khaste nabashin), which is the colloquial plural. Some people add khoda ghovat (God give you strength) before or after it. خسته نباشی، خدا قوت is the ultimate combo. It’s like a double shot of espresso for the soul. In some regions, they might say مانده نباشی (mande nabashi), which means the same thing. This is more common in Afghanistan and parts of Khorasan. If you use mande nabashi in Tehran, they’ll know you’re a real language nerd. It’s like using a regional dialect in English—it shows character. Just don't mix them up in the same sentence or you'll sound like a confused textbook.

Is it always positive? Mostly, yes. It’s a sign of respect. Only when used with a very specific 'tone' and to someone who hasn't worked can it be sarcastic. Does it require a specific response? Yes, usually سلامت باشی (salamat bashi) which means 'may you be healthy.' It’s the standard counter-move. Can I say it to a group? Yes, use خسته نباشید. It covers everyone from a football team to a room full of developers. Is it used in books? Not much. It’s a spoken, living phrase. You’ll find it in movie scripts and WhatsApp chats, but rarely in a formal poem about roses and nightingales. Does it expire? No, people have been saying this for centuries and will probably say it to the robots who eventually take over our jobs. Even robots don't want to be 'khaste.'
