覚え方のコツ Memory Tip
requires は require「必要とする・要求する」の三人称単数現在形。主語が this job、the game、learning a language のように単数扱いなら、語末に -s を付けて requires /rɪˈkwaɪərz/ と発音する。require + 名詞、require 人 to do、require that節という型で覚えると使いやすい。
Begin with the base verb require, meaning “need” or “demand.” For a third-person singular subject in the present tense, add -s: require → requires, pronounced with a final /z/ sound. Notice typical singular subjects: This job requires time; The game requires two players; Learning a language requires practice. Useful patterns include require something, require someone to do something, and require that something be done. Unlike want, require presents the thing as necessary or officially demanded, not merely desired.

requires の語源・成り立ち Etymology
requires は require「必要とする」の三単現で、語源はラテン語 requirere「求める・問いただす」。re- + quaerere「探す」から成り、「強く求める」感覚が「必要とする」へつながる。関連語に inquire, query。
"Radius" comes from Latin "radius," which first meant a spoke of a wheel or a ray of light. Because a spoke stretches from the center outward, the word later became the geometric term for a line from the center of a circle. Related English words include "radiate" and "radio," which keep the older idea of rays spreading outward.
