Part of Speech: Verb

HSK Level: HSK 5

Concise Definition: To break a physical or abstract connection, resulting in separation.

In a Nutshell: 断开 (duànkāi) is the action of taking something that was connected and making it separate. Think of it as pulling a plug from a socket, cutting a rope in two, or a phone call dropping. It implies a definitive interruption or severance, whether it's an electrical circuit, an internet signal, or a human relationship.

断 (duàn): This character means “to break” or “to cut off.” It's a pictograph showing an axe or blade (斤) cutting through threads (幺 + 幺). This vividly illustrates the act of severing something.

开 (kāi): While it often means “to open,” here it acts as a resultative complement, indicating a state of being “apart” or “away from each other.” It shows the result of the action.

Together, 断开 (duànkāi) literally means “to break apart,” perfectly capturing the idea of disconnecting something that was once whole or linked.

The Sound of Finality: While 断开 is a common, neutral term in technical contexts, its use in relationships carries a strong sense of finality. To 断开联系 (duànkāi liánxì), or “sever contact,” is a deliberate and decisive action. It's much stronger than simply drifting apart; it's a conscious choice to cut ties.

Comparison to Western Concepts: The English phrase “to cut someone off” is a very close equivalent in social situations. However, 断开 lacks the ambiguity of terms like “taking a break” or “ghosting.” When someone says they have 断开 contact, there is little room for misinterpretation—the connection has been intentionally severed. This reflects a preference for clarity in expressing the end of a relationship, even if the act itself is difficult. It's less about avoiding confrontation and more about defining a new reality where a connection no longer exists.

断开 vs. 断 (duàn): In casual speech, especially about networks, you can often just use 断 (duàn). For example, “网断了” (Wǎng duàn le - “The internet is down”). 断开 is a more complete verb phrase that emphasizes both the action of breaking and the resulting state of being apart. It is slightly more formal and precise.

连接 (liánjiē) - To connect, to link. The direct antonym of 断开.

分手 (fēnshǒu) - To break up (romantically). A very specific type of relationship “disconnection.”

断绝 (duànjué) - To sever completely. This is even stronger and more formal than 断开, often used in the phrase 断绝关系 (duànjué guānxì), meaning to cut off all relations, often with family.

中断 (zhōngduàn) - To interrupt, to suspend. Implies a temporary pause or disruption in a process, whereas 断开 often suggests a more complete break.

分开 (fēnkāi) - To separate, to move apart. It describes the state of being physically apart but doesn't necessarily imply that a connection was forcefully broken.

掉线 (diàoxiàn) - Literally “to drop the line.” A colloquial and modern term used specifically for getting disconnected from the internet or an online game.

断 (duàn) - To break, snap. The root character of 断开 and a verb on its own, often used in a more casual way (e.g., 绳子断了 - the rope snapped).
