覚え方のコツ Memory Tip
原形 operate に過去・過去分詞の -d だけを加えた規則変化で、発音は /ˈɑːpəreɪtɪd/ など語末が /ɪd/ になる。ここでは operated by a button / worker の形で、「ボタンや人によって操作・運転された状態」を表す過去分詞形容詞として覚える。
Start with the base verb operate. Because it already ends in silent e, form the past tense and past participle by adding only -d: operate → operated. The ending is pronounced /ɪd/ after the final /t/ sound. In this entry, operated describes something controlled or made to work, especially a machine, crane, or door. The pattern be operated by identifies the controller or mechanism: a crane is operated by a trained worker, and a door is operated by a button. Link it with operator, the person who controls equipment, and operation, the act or process involved.

operated の語源・成り立ち Etymology
operated は operate の過去分詞で、語源はラテン語 operari「働く・作用する」です。土台の opera / opus は「仕事・作業」。だから「操作された」は、本来「働くようにされた・作動させられた」という感覚です。関連語は operation, operator。
Operated is the regular past-tense and past-participle form of operate. Operate comes from Latin operari, meaning to work, labor, or perform, based on opus or oper-, meaning work. English developed several senses from the central idea of working or causing something to work, including running machinery and controlling equipment. Related formations include operation, operator, and operational. The adjectival use of operated arises from the past participle in passive expressions such as operated by a worker.
