    Explanation

    The Japanese noun '効力 (こうりょく)' refers to the effectiveness, efficacy, or power of something to produce a desired result. It is often used in legal, medical, or technical contexts to describe the force or validity of a rule, law, medicine, or method. For example: This medicine has lost its effectiveness「この薬は効力を失った」(このくすりはこうりょくをうしなった). The new law will take effect next month「新しい法律は来月効力を持つ」(あたらしいほうりつはらいげつこうりょくをもつ). Note that '効力' emphasizes the practical impact or result of something, rather than its theoretical potential.
