**there is no one who doesn't**

Pattern: `Không ai (là) không + [verb] · Không + [noun] + nào (là) không + [verb]`

Level: B2 (our estimate) · Register: everyday

Typed without accents: khong ai khong, khong … nao khong

*Không ai không* + verb means "there's no one who doesn't", a strong way of saying everyone: *Ở xóm này không ai không biết bà Tư*, everyone in this neighbourhood knows Bà Tư. The two negatives cancel out, as in English "there isn't a soul who doesn't …".

It also works with a noun and *nào*: *không* + noun + *nào* + *không* + verb. *Không nhà nào không có xe máy*, there isn't a house without a motorbike. *Là* can go before the second *không* for extra weight: *Không ai là không thích được khen.*

The plain way to say everyone is *ai cũng*: *Ai cũng biết bà Tư.* Use *không ai không* when you want to stress that there are no exceptions at all. It suits a story, praise, or a point you're making with some feeling, and it's used in writing as well as in speech.

Count the negatives when you hear it. With one, *Không ai biết* means nobody knows; with two, *Không ai không biết* means everybody does.

## Examples

- Ở xóm này không ai không biết bà Tư. — Everyone in this neighbourhood knows Bà Tư.
- Không ai là không thích được khen. — There's no one who doesn't like being praised.
- Ở quán này, không món nào là không ngon. — There isn't a single dish at this place that isn't good.
- Saigon: Trong hẻm này không nhà nào không có xe máy. | Hà Nội: Trong ngõ này không nhà nào không có xe máy. — There isn't a house in this alley without a motorbike.
