The moment two halves come apart: 开

Where the picture shows up in 开

1. 1

   the door parts

   麻烦你开一下门。

   máfan nǐ kāi yíxià mén

   Could you get the door, please?

2. 2

   release what was standing still

   我不会开车。

   wǒ bú huì kāichē

   I can't drive.

   开车 isn't opening the car — it's releasing a parked car into motion.

3. 3

   let the flow through

   太热了，把空调开一下。

   tài rè le, bǎ kōngtiáo kāi yíxià

   It's boiling in here — turn on the AC.

4. 4

   the gathering opens up

   我们下午三点开会。

   wǒmen xiàwǔ sān diǎn kāihuì

   We have a meeting at three this afternoon.

5. 5

   write it out on paper

   医生给我开了药。

   yīshēng gěi wǒ kāi le yào

   The doctor wrote me a prescription.
