覚え方のコツ Memory Tip
oiled は oil「油を差す・塗る」に -ed を付けた過去形・過去分詞で、形容詞なら「油を塗った状態」。oil は母音字で終わるが、そのまま -ed を加え、発音は /ɔɪld/ と一音節になる。oiled chain、oiled surface、oiled hinges のように、摩擦やきしみを減らす対象と組み合わせて覚える。
Start with the noun oil, then use it as a verb meaning “to apply oil.” Add -ed without changing the base spelling: oil → oiled. It is pronounced /ɔɪld/ as one syllable; the ending does not add a separate /ɪd/ syllable. Picture an oiled chain moving smoothly, oiled hinges becoming quiet, or an oiled surface being wiped with a cloth. These common combinations emphasize that oil has already been applied, so oiled can function as a past participle or as an adjective describing the resulting condition.

oiled の語源・成り立ち Etymology
oiled は oil + -ed で「油を施した」という形。oil は古フランス語 oile、ラテン語 oleum、さらにギリシャ語 elaion「オリーブ油」にさかのぼるため、もとは「オリーブ由来の油を塗った」という感覚が土台にある。関連語は olive, oleaginous。
Oiled is formed from the verb oil plus the past-participle ending -ed. Oil entered English through Old French oile, from Latin oleum, “olive oil” or “oil,” ultimately related to Greek elaion, “olive oil.” The verb developed naturally from the noun and means “to apply oil.” Oiled therefore literally describes something that has had oil put on it, especially for lubrication, protection, or finishing.
