Yes. Every word comes from how people talk in group chats, on TikTok and over a beer, and is reviewed by a native speaker before it goes live. Each entry also tells you where it is used: North, Centre or South.
That is exactly what the spice rating is for. Every word is rated from harmless to vulgar, with a note on who you can safely say it to. You learn the register before you learn the word.
The starter lesson is free, with no account and no email. The themed packs are one-time purchases that you keep forever, not a subscription.
Duolingo teaches textbook Vietnamese, and it does that well. vietslang covers the other half: the words your Vietnamese friends actually text you, the ones no course or dictionary explains.
No. Every word comes with its literal meaning, what it really means, and a real example sentence with an English translation, so complete beginners can play too.
Pay once. Keep it for good. Your progress follows you.
