**bouts**

Pattern: `cơn + mưa / bão / sốt / giận`

Level: A2 (our estimate) · Register: everyday

Typed without accents: con

*Cơn* is the classifier for things that come over you, or over the sky, for a while and then pass: *cơn mưa* (a shower), *cơn bão* (a storm), *cơn sốt* (a bout of fever), *cơn đau* (a spell of pain), *cơn giận* (a fit of anger).

Like any classifier, it goes between a number or *này* / *đó* and the noun: *một cơn mưa lớn* (a heavy shower; in Hà Nội *mưa to*), *cơn bão này* (this storm).

Often you don't need it at all. *Trời mưa* means it's raining, and *Em bị sốt* means I've got a fever. Use *cơn* when you talk about one particular shower or bout: when it came, how long it lasted, how bad it was. *Cơn mưa hồi chiều lớn quá.* That shower this afternoon was so heavy.

You'll hear it in the weather news, where storms are numbered: *cơn bão số 3*. *Trận* is close and also goes with rain and storms, *trận mưa*; it's the word for a match, too: *trận bóng đá*.

## Examples

- Saigon: Cơn mưa hồi chiều lớn quá. | Hà Nội: Cơn mưa chiều nay to quá. — That shower this afternoon was so heavy.
- Cơn bão này mạnh lắm. — This storm is very strong.
- Tối qua bé lên cơn sốt cao. — Last night the little one had a high fever.
- Saigon: Chờ hết cơn mưa này rồi mình đi nha. | Hà Nội: Chờ hết cơn mưa này rồi mình đi nhé. — Let's wait for this shower to pass, then go.
