**any … whatsoever**

Pattern: `bất cứ / bất kỳ + [question word or noun] + (… cũng)`

Level: B1 (our estimate) · Register: everyday

Typed without accents: bat cu, bat ky

*Bất cứ* and *bất kỳ* mean "any … at all". Put either one in front of a question word or a noun: *bất cứ ai* (anyone at all), *bất cứ lúc nào* (any time), *bất kỳ ngày nào* (any day). They mean the same; *bất cứ* is the one you'll hear more in speech, and *bất kỳ* (also spelled *bất kì*) is common in writing.

In a statement, *cũng* goes before the verb, just as in *ai cũng* (everyone) and *lúc nào cũng* (always), which you know. *Bất cứ* makes them sound complete, "any one at all, without exception": *Bất cứ ai cũng làm được.* Anyone can do it. In relaxed talk the plain question word is often enough: *Anh gọi em lúc nào cũng được.*

In *nếu* (if) sentences, offers and notices, there's no *cũng*: *Nếu chị cần bất cứ gì, cứ nói em nha.* If you need anything at all, just tell me. At the end of emails and notices you'll see the written formula *Nếu có bất kỳ thắc mắc nào, xin vui lòng liên hệ*, if you have any questions, please get in touch.

## A common mistake

✗ Bất cứ ai làm được.

✓ Bất cứ ai cũng làm được.

In a statement, *bất cứ* needs *cũng* before the verb, just as *ai cũng* does.

## Examples

- Bất cứ ai cũng làm được. — Anyone can do it.
- Anh gọi em bất cứ lúc nào cũng được. — You can call me any time at all.
- Saigon: Nếu chị cần bất cứ gì, cứ nói em nha. | Hà Nội: Nếu chị cần bất cứ gì, cứ nói với em nhé. — If you need anything at all, just tell me.
- Nếu có bất kỳ thắc mắc nào, xin vui lòng liên hệ. — If you have any questions, please get in touch. (in an email or notice)

## Variant of

- [Everyone, everything, always: ai cũng, gì cũng, lúc nào cũng](https://vietnamesebuddy.com/grammar/qword-cung-every/): every- / any-
