control of something harmful
The act of stopping something bad from spreading or becoming bigger.
用法模式：
containment of [something harmful/unwanted]
常见错误：
Learners sometimes confuse "containment" with "container" (a physical object) or "contentment" (a feeling of happiness). Also, learners may say "containment for the virus" instead of the more natural "containment of the virus"; use "containment of + [problem]".
近义词
control (More general word; can refer to any kind of influence or restraint, not only stopping spread or growth.)
|
suppression (Emphasizes actively forcing something down or stopping it, often more forceful than general 'containment'.)
反义词
spread (Refers to something moving out and becoming larger or wider, which containment tries to prevent.)
|
escalation (Focuses on a problem becoming more serious or intense, the opposite of keeping it under control.)

foreign policy to limit a rival
A plan in politics or war to stop another country or group from growing stronger or bigger, especially used for U.S. plans against the Soviet Union in the past.
用法模式：
a policy/strategy of containment (of [rival])
常见错误：
Learners may incorrectly use this political sense for everyday problems, saying things like "containment of my stress" when the general control sense (meaning 1) is intended. This sense usually appears with words like "policy", "strategy", "doctrine", and in discussions of international politics or the Cold War.
近义词
deterrence (Related foreign-policy idea that focuses on discouraging attacks, whereas containment focuses on stopping expansion of influence.)
|
limitation (More general and less technical; does not specifically imply a strategic foreign policy.)
反义词
appeasement (In political history, refers to giving concessions to a rival power, which is often contrasted with containment.)
|
expansionism (Describes the policy of growing a state's power or territory, which containment tries to prevent.)

keeping substances fully enclosed
The way something, like a liquid or gas, is kept inside walls or a container so it does not leak out.
用法模式：
containment of [substance] / [adjective] containment system
常见错误：
Learners may not realize this is a technical use and might overuse it in general speech, where simpler words like "keeping in" or "holding" are more natural. Also, "containment" is uncountable here; do not say "a containment" when you mean "a containment system" or "a containment structure".
近义词
enclosure (Focuses on the closed space around something, not specifically on preventing leaks or environmental release.)
|
confinement (Stresses something being held in a limited space; can be used for people or animals, not just substances.)
反义词
release (The act of letting a substance go out into the environment, which proper containment tries to prevent.)
|
leakage (The unwanted escape of a substance through a barrier, often caused by failed containment.)

safety structure preventing escape
A special building or structure that keeps dangerous materials inside so they cannot get into the air, water, or ground.
用法模式：

常见错误：
Learners might treat this as a general word for any container. In this technical sense it usually appears as "containment building", "reactor containment", or "containment structure" in discussions of nuclear or chemical safety.
近义词
protective structure (More general; does not specifically imply preventing the escape of hazardous materials.)
反义词
open facility (A site without sealed protective structures, where substances are not fully enclosed.)
