state of needing support
A state where a person, group, or thing needs someone or something else in order to live, work, or do well, and cannot easily do it alone.
用法パターン：
[someone]'s dependency on [something/someone]
よくある間違い：
Learners often confuse "dependency" and "dependence". In most general uses, both are correct, but "dependence" is slightly more common. "Dependency" is especially frequent when followed by "on" (e.g., "dependency on foreign oil"). Another common mistake is using the wrong preposition, such as *"dependency of"* instead of the natural *"dependency on"*.
類義語
dependence (Very close in meaning; slightly more common overall and a bit more general, while "dependency" often suggests an unhealthy or one-sided need or is used in specific technical terms.)
|
reliance (Emphasizes trusting or counting on something or someone, without always implying loss of independence.)
対義語
independence (Describes being able to act or live without needing support from others, which is the opposite of dependency.)

addiction to a substance or behavior
A problem where someone cannot stop using a drug, alcohol, or a behavior because their body or mind now needs it.
用法パターン：
dependency on [a substance/behavior]
よくある間違い：
Learners sometimes use "dependency" to mean a simple habit, when it usually implies a serious medical or psychological problem. For weaker habits, "habit" or "tendency" is more natural. Also, remember to use the preposition "on" (e.g., "dependency on alcohol"), not *"dependency of alcohol"*.
類義語
addiction (The most common everyday word; "dependency" is often used in medical or formal contexts and can sound slightly more clinical.)
対義語
sobriety (Refers to living without alcohol or drugs, which is the opposite condition of alcohol or drug dependency.)

required component in computing
In software or technical work, something (like a library or tool) that a program or project must have so it can work.
用法パターン：
[a program] has a dependency on [a library/tool]
よくある間違い：
Learners sometimes think "dependency" here means a person who depends on someone. In technical contexts, it almost always means a required component (like a library or service). Another mistake is using a plural verb with "dependencies" but then talking about only one item; be careful to match singular/plural correctly.
類義語
requirement (A general word for something needed; "dependency" is more specific in technical fields, especially software development.)
対義語
standalone (Describes software or systems that do not need extra components, which is the opposite of having many dependencies.)

territory controlled by another state
A place or region that is ruled by another country and does not have complete political freedom.
用法パターン：
a dependency of [a country]
よくある間違い：
Learners may confuse this political meaning with the general sense of needing support. In this sense, "dependency" is almost always used with places and often followed by "of" or used with adjectives like "overseas" or a country name (e.g., "a British dependency").
類義語
territory (More general; "dependency" stresses the lack of full independence and control by another state.)
対義語
sovereign state (A fully independent country that governs itself, which is the opposite of a dependency.)

secondary building belonging to a main house
A small building, like a stable or store room, that is part of a big house or estate and used to support it.
用法パターン：
the house and its dependencies
よくある間違い：
Because this sense is rare, learners may wrongly apply the common meaning of "dependency" (needing support) to architectural contexts. In descriptions of estates or old houses, "dependencies" usually means extra buildings, not emotional or financial need.
類義語
outbuilding (A common modern term for a smaller building near a main one; "dependency" is rare and sounds old-fashioned or literary.)
対義語
main house (Refers to the principal building, in contrast to the smaller supporting buildings called dependencies.)
