覚え方のコツ Memory Tip
intervenes は intervene の三人称単数現在形で、主語が he、she、a teacher、the court など単数のとき語尾に -s を付けます。inter-「間に」＋ vene「来る」と捉え、争いの当事者の間へ第三者が入る図を想像しましょう。intervene in a dispute、intervene when trouble starts が典型で、末尾は「ズ」と発音します。
Start with the base verb intervene and add -s because the subject is third-person singular in the present tense: a teacher intervenes, the court intervenes, or she intervenes. The word’s parts suggest “come between,” so picture a mediator stepping between two people when an argument becomes too tense. Useful patterns include intervene in a dispute and intervene when someone is treated unfairly. The final -s is pronounced /z/ because intervene ends in a voiced sound. Keep the form tied to a single present-tense subject; with plural subjects or I, you, and they, use intervene.

intervenes の語源・成り立ち Etymology
intervenes は intervene の三単現で、語源はラテン語 intervenire「間に来る」です。inter-「間に」+ venire「来る」、さらに -s は現在形の三単現なので、「間に来て手を入れる」から『介入する』になったとわかります。関連語は intervention、convene。
Intervenes is the third-person singular present form of intervene, with the regular ending -s. Intervene comes from Latin intervenire, “to come between,” formed from inter-, “between,” and venire, “to come.” The physical idea of coming between people or events developed into the modern sense of entering a dispute, process, or difficult situation in order to influence it. Related formations such as intervention preserve the same Latin elements and the same central image.
