What does 开 mean?

开 (kāi) is one of the most flexible verbs in Chinese.

Its core meaning is 'to open,' but native speakers extend it freely: 开门 (open a door), 开车 (drive a car), 开灯 (turn on a light), 开会 (hold a meeting), 开始 (start). English forces a different verb for each of these — open, drive, turn on, hold, start — while Chinese uses 开 because the underlying idea is the same: setting something into motion or breaking it out of a closed state.

The opposite is 关 (guān, 'close / shut off'), which pairs with 开 across all these uses: 关门 close the door, 关灯 turn off the light, 关电视 turn off the TV. Register is neutral and the verb works in any context.

Memory hook: The traditional form 開 shows hands lifting a bolt off a door — the original 'open' image survives in every modern use of 开.
