开门

Just pop 开门 (kāi mén) after the thing you're opening. Or, if it’s obvious, you can just say 开门 on its own. For example, you can say 开我家门 (kāi wǒ jiā mén) - 'open my house door.' Or, if someone is knocking, you can just shout 开门! (kāi mén!) meaning 'Open the door!'. It’s a verb-object structure, plain and simple. You’ll hear it constantly, so it’s a must-know.

Imagine your friend is at your apartment. You text: 我到了，快开门！ (Wǒ dào le, kuài kāi mén!) - 'I'm here, open the door quickly!'. Or, you're watching a movie, and a character needs to get inside: 他敲了敲门，然后门开了。 (Tā qiāo le qiāo mén, rán hòu mén kāi le.) - 'He knocked on the door, then the door opened.' It’s used in everyday speech, movies, and even instructions. It’s the bread and butter of door-related actions.

Use 开门 whenever you need to express the action of opening a door. This includes physical doors, like your home, office, or car. It's also used when you want someone to let you in. If you're talking about the general act of opening, like in a story, 开门 works. It's perfect for everyday conversations and simple descriptions. Think of it as your default setting for 'door opening.'

Don't use 开门 for metaphorical 'opening doors,' like 'opening doors of opportunity.' That requires different, more abstract vocabulary. Also, if you're talking about starting a business or a shop, you might use 开业 (kāi yè) instead. 开门 is strictly for physical doors. Using it metaphorically might sound a bit odd, like saying 'open the opportunity door' in English – it’s understandable but clunky. Stick to the literal for this one!

Learners sometimes get confused with similar-sounding verbs or try to force 开门 into abstract situations. A common slip-up is using it for starting something new. For instance, saying 开门我的公司 (kāi mén wǒ de gōng sī) instead of 开办我的公司 (kāi bàn wǒ de gōng sī) or 开业我的公司 (kāi yè wǒ de gōng sī). Another mistake is overthinking it and trying to add unnecessary words. Keep it simple!

There aren't many direct synonyms for the literal act of opening a door. However, 打开 (dǎ kāi) is a more general verb meaning 'to open' and can also be used for doors, but it feels slightly more formal or descriptive. 推开 (tuī kāi) means 'to push open,' and 拉开 (lā kāi) means 'to pull open,' specifying the action. For starting a business, 开业 (kāi yè) is the correct term.

Sometimes you'll see 开门 used in slightly different contexts. For example, 开门见山 (kāi mén jiàn shān) is an idiom meaning 'to get straight to the point,' literally 'open the door and see the mountain.' It’s a fixed phrase, though! In spoken language, people might just say 开 (kāi) if the context of 'door' is super clear. Like, 'Is the door open?' might become 'Is it open?' if you're already looking at it.
