覚え方のコツ Memory Tip
requiring は require の語末 e を落として -ing を付けた現在分詞・動名詞で、require → requiring。発音は /rɪˈkwaɪərɪŋ/。need よりかためで、require time、require a password、require someone to sign in のように、条件として不可欠な物や行為を求める場面で覚える。
Requiring is made from require by dropping the final silent e and adding -ing: require becomes requiring. The pronunciation continues the sound pattern of require: /rɪˈkwaɪərɪŋ/. Associate it with a condition that must be satisfied. A job may be requiring more time, a system may be requiring a password, and a rule may be requiring visitors to sign in. Require is generally more formal and stronger than need because it often presents something as a condition, demand, or official necessity. The -ing form can describe an ongoing situation or name the act of imposing a requirement.

requiring の語源・成り立ち Etymology
ラテン語 requirere（探し求める）から古フランス語 requerre を経て英語に。re-（繰り返し）+ quaerere（求める）の構成。関連語: query, request。「何度も求める」→「なくてはならない」と必要性の意味が強まった。
Requiring is the -ing form of require, made by dropping the final e before adding -ing. Require entered English through Old French requerre and ultimately comes from Latin requirere, meaning “to seek, ask for, or demand.” The Latin verb combines re- with quaerere, “to seek or ask.” Over time, the sense of seeking or demanding something developed into the modern idea that a condition, object, or action is necessary. Query is historically related through the same Latin root.
