1
officially reverse a decision
To say that an earlier decision, ruling, or judgment is no longer valid and must be changed.
用法パターン：
to overturn [a decision / ruling / law / conviction]
よくある間違い：
Learners sometimes confuse "overturn" with "turn over". "Overturn" in this sense is used for abstract things like decisions, rulings, and laws, not for physical objects. Say "overturn a decision" but "turn over a page" or "turn over the meat".
類義語
reverse (Very close in meaning, common in legal and official contexts like court decisions.)
|

|
invalidate (Stresses making something no longer legally or officially acceptable.)

2
knock something over
To make something fall onto its side or top, usually by hitting or pushing it.
用法パターン：
to overturn [a car / table / boat / container]
よくある間違い：
Learners sometimes use "overturn" for small everyday objects where "knock over" or "tip over" sounds more natural (e.g. "overturn a cup"). While not wrong, native speakers more often say "knock over a cup" and reserve "overturn" for larger or more serious things like cars, boats, or tables.
類義語
tip over (Very close in meaning; slightly more informal and common in everyday speech.)
|
knock over (Emphasizes an accidental or careless push that makes something fall.)
対義語

3
vehicle or boat turns over
For a car, truck, boat, or similar thing to roll onto its side or top, usually by accident.
用法パターン：
[a vehicle / boat] overturns
よくある間違い：
Learners sometimes say "the car was overturned" when no outside force is mentioned. In accident reports, English often says "the car overturned" (intransitive) when the accident itself caused the rollover, and "the car was overturned by protesters" (passive, transitive) when someone caused it.
類義語
roll over (Common in traffic reports; often used for vehicles turning onto their side or roof.)
|
capsize (Used mainly for boats and ships turning over in water.)
対義語
remain upright (Means that the vehicle or boat stays in its normal standing position and does not overturn.)

destroy a system or government
To cause a government, system, or set of rules to end or lose power, often in a dramatic way.
用法パターン：
to overturn [a government / system / order / tradition]
よくある間違い：
Learners often use "overthrow" in all cases and are unsure when to use "overturn". "Overthrow" is more specific to removing a government, while "overturn" can refer more broadly to destroying or replacing a system, order, or set of traditions, not only a government.
類義語
overthrow (Very close in political contexts; often more clearly connected to replacing a government.)
|
topple (Suggests making a government or leader fall from power, sometimes with less focus on complete destruction of the system.)
|
dismantle (Focuses on taking a system apart step by step rather than sudden force.)
対義語

|
