覚え方のコツ Memory Tip
intersects は原形 intersect に三人称単数現在の -s を付けた形で、発音は語末が /ts/ になります。主語が this road、the blue line、the trail のような単数のときに使い、intersect A や intersect with A の形で「線・道路などが一点で交差する」と覚えましょう。intersection「交差点」も手掛かりになります。
Begin with the base verb intersect and add -s because the subject is third-person singular: a road intersects another road, or a blue line intersects a red line. Since intersect already ends in /t/, the final letters of intersects are pronounced together as /ts/. The structure inter- plus a root meaning “cut” suggests one line cutting across another. Picture two lines meeting at a single point, and connect the verb with intersection, the familiar noun for a place where roads meet. Both intersect something and intersect with something occur, though the direct-object pattern is especially concise in geometry and route descriptions.
例文
This road intersects the main street near the station.

intersects の語源・成り立ち Etymology
intersects は inter-「〜の間で」＋ sect「切る」から成る intersect の三人称単数形です。sect はラテン語 secare「切る」に由来し、section や dissect と同根なので、「互いの間を切るように横切る」ことから交差する意味になりました。
Intersects is the third-person singular present form of intersect, created by adding -s to the base verb. Intersect comes from Latin intersecare, formed from inter-, “between” or “among,” and secare, “to cut.” Its literal structure suggests cutting between or across. The same Latin root appears in section and dissect. The geometric and spatial sense developed naturally from lines or routes crossing one another.
