Saigon: hèn chi; hèn gì | Hà Nội: thảo nào

When something suddenly makes sense, start with *hèn chi*: "no wonder", "that explains it". What follows is the thing you now understand, and the reason has usually just been said: *Hôm nay chủ nhật hả? Hèn chi đường vắng.* It's Sunday? No wonder the roads are empty.

*Hèn gì* means the same and is just as common in Saigon: *Chị ấy ở Mỹ lâu rồi, hèn gì giỏi tiếng Anh vậy.* She lived in America for years, no wonder her English is so good. In Hà Nội people say *thảo nào*: *Thảo nào đường vắng thế.* You'll be understood with any of them.

On its own, *Hèn chi!* is a whole reply: "That explains it!" or "Ah, so that's why!" It's a friendly way to show you've followed what someone told you.

*Vậy* at the end (in Hà Nội, *thế*) often adds surprise: *hèn chi đông vậy*, no wonder it's so crowded. For a reason you're giving yourself, rather than one you've just discovered, use *vì* or *tại vì*.
