覚え方のコツ Memory Tip
原形 prevent に三人称単数現在の -s を付けた形で、語末は /s/ と発音する。主語は a helmet、this rule、regular cleaning のような単数または不可算名詞になる。prevent injuries のほか、prevent someone from doing の形で「人が〜するのを妨げる」と覚える。
Prevents is the third-person singular present form of prevent. Add -s to the base verb and pronounce the ending /s/ because prevent ends with the voiceless sound /t/. Use it when the subject is singular or uncountable: “A helmet prevents injuries” and “Regular cleaning prevents problems.” Learn two core patterns: something prevents a problem, and something prevents someone from doing something. Both express action taken early enough to stop an unwanted event or activity from happening.
例文
A helmet prevents head injuries.
ヘルメットは頭のけがを防ぎます。
This rule prevents mistakes.
この規則はミスを防ぎます。
Regular cleaning prevents many problems.
定期的な掃除は多くの問題を防ぎます。

prevents の語源・成り立ち Etymology
prevents は prevent の三単現で、ラテン語 praevenire に由来します。prae-「前に」+ venire「来る」で、もとは「先回りして来る」ことから、相手より先に手を打って「防ぐ」の意味になりました。関連語は intervene, convene。
Prevents is formed from prevent with the third-person singular present suffix -s. Prevent comes from Latin praevenire, composed of prae-, “before,” and venire, “to come.” It originally carried the idea of coming before or anticipating something. That developed into the modern sense of acting in advance so that an event cannot occur. Words such as intervene and convene contain forms derived from the same Latin verb for coming.
