1
causing severe damage or destruction
causing very serious harm or damage, sometimes destroying something completely over time.
用法パターン：
[something] is ruinous to [something]
よくある間違い：
Learners sometimes confuse 'ruinous' with 'ruined'. 'Ruinous' describes something that causes great harm (a ruinous policy, a ruinous mistake), while 'ruined' describes something that has already been destroyed or badly damaged (a ruined city, a ruined cake). They also overuse it in casual speech, where 'very harmful' or 'terrible' may sound more natural.
類義語
disastrous (Stresses a very bad result; slightly more general and a bit less formal than 'ruinous'.)
対義語
beneficial (Describes something that produces good, helpful effects instead of serious harm.)

extremely expensive; financially destructive
so expensive that it can badly damage your money situation or even make you lose everything.
用法パターン：
[cost or price] is ruinous for [someone]
よくある間違い：
Learners sometimes use 'ruinous' to mean simply 'very expensive' in everyday, light situations (e.g., a pricey coffee). In English, 'ruinous' normally suggests serious financial harm, not just something a bit overpriced.
類義語
exorbitant (Focuses more narrowly on an unreasonably high price; 'ruinous' emphasizes the damaging effect on finances.)
対義語
affordable (Describes a price that people can pay without serious financial difficulty, the opposite of 'ruinous' cost.)

用法パターン：

よくある間違い：
Learners may think this meaning is common in everyday speech. In modern English, people more often say 'falling down', 'run‑down', or 'in ruins'; 'ruinous' here is mostly written or literary.
類義語
dilapidated (Very close in meaning but slightly more common in everyday description of old, badly kept buildings.)
対義語
