覚え方のコツ Memory Tip
applied は apply の過去形・過去分詞で、語末の y を i に変えて -ed を付けます。発音の -ed は /d/ です。形容詞では applied science「応用科学」のように「実用の」、受け身では a rule was applied「規則が適用された」となります。apply A to B「AをBに当てはめる」の形から覚えましょう。
Connect applied to apply and notice the spelling change: when -ed is added, the final y becomes i, producing applied. Its ending is pronounced /d/, not as a separate syllable. Keep the pattern apply A to B in mind: a rule can be applied to a case, and a discount can be applied to an order. As an adjective before a noun, applied often contrasts with purely theoretical, as in applied science or applied research. The shared memory image is something being placed onto a real situation and made practically effective.

applied の語源・成り立ち Etymology
ラテン語 applicare（貼り付ける、結びつける）から。ad-（～へ）+ plicare（折る・重ねる）で「何かに折り重ねる→当てはめる」が原義。理論を実践に「当てはめた」状態が applied。complicate（複雑にする）、reply（返答）も同根。
Applied is the past-tense and past-participle form of apply, with final y changing to i before -ed. Apply comes through Old French from Latin applicare, “to attach or join.” That Latin verb combines ad-, “to,” assimilated to ap- before p, with plicare, “to fold.” The historical image of bringing or attaching one thing to another developed into modern senses such as putting a rule, method, knowledge, or treatment into practical use.
