कोई बात नहीं

You can use it as a standalone sentence. If someone bumps into you, just say Koi baat nahi. If someone thanks you for a coffee, say Koi baat nahi. It works perfectly at the beginning or end of a sentence too. It is incredibly flexible and fits almost anywhere in a conversation. You do not need to worry about complex grammar or gender rules with this one.

Use it when someone says 'Sorry' for being five minutes late. Use it when a waiter apologizes for a slight delay. It is also the standard response to 'Dhanyavad' (Thank you) in casual settings. Think of it as your 'don't sweat it' button. It is great for texting when a friend cancels plans. It keeps the vibe chill and prevents things from getting awkward.

Do not use it for very serious mistakes or deep tragedies. If someone loses their job, Koi baat nahi might sound dismissive or cold. Avoid using it in extremely high-stakes formal environments, like a court of law. In those cases, more formal phrases are better. Also, do not use it if you are actually very upset. It is a phrase of forgiveness, not a way to hide your true anger.

Indian culture places a high value on hospitality and 'adjusting.' This phrase reflects that 'Chalta Hai' (it goes/it's okay) attitude. It shows that you are a large-hearted person who does not hold onto small grievances. It bridges the gap between strangers and friends alike. It is a linguistic hug that says 'we are cool.'

You might hear Koi baat nahi hai which is just a slightly longer version. Some people say Arre, koi baat nahi to add a bit of warmth or emphasis. In very casual slang, younger people might just say Koi nahi. But the standard version is your safest bet for looking like a pro.
