**that (fact just mentioned)**

Pattern: `[verb or preposition] + điều đó / việc đó / chuyện đó / vậy / thế`

Level: B1 (our estimate) · Register: everyday

Typed without accents: dieu do, viec do, chuyen do

English uses "that" or "it" for a fact or a situation just mentioned: "I didn't know that", "Don't worry about it". Vietnamese rarely uses *nó* for this, and *cái đó* is first of all a thing you can point at, though casual speech stretches it: *Cái đó em không biết.* The careful choice is a word for the kind of "that" you mean, with *đó* after it.

*Chuyện đó* (that matter, that story) is the everyday one in speech: *Em biết chuyện đó rồi.* I know about that already. *Việc đó* is a task, something to be done: *Việc đó để anh lo.* Leave that to me. *Điều đó* is a fact or an idea, and it's the usual choice in writing: *Điều đó rất quan trọng.* That's very important.

After *nói* (say), *nghĩ* (think) and *làm* (do), people usually just say *vậy*, "so, like that": *Em không nghĩ vậy.* I don't think so. *Đừng nói vậy.* Don't say that. In Hà Nội it's *thế*: *Đừng nói thế.*

Use *này* (this) instead of *đó* for something you're about to bring up: *Chuyện này em chưa kể ai hết.* I haven't told anyone this. In writing, and in Hà Nội, *ấy* can replace *đó*: *điều ấy*, *việc ấy*.

## A common mistake

✗ Đừng lo về nó.

✓ Đừng lo chuyện đó.

*Nó* refers to a thing, an animal or a child, not to a situation. Use *chuyện đó*, or just leave "it" out: *Đừng lo.*

## Examples

- Em biết chuyện đó rồi. — I already know about that.
- Việc đó để anh lo. — Leave that to me.
- Saigon: Em không nghĩ vậy. | Hà Nội: Em không nghĩ thế. — I don't think so.
- Điều đó rất quan trọng với tôi. — That's very important to me.
