覚え方のコツ Memory Tip
train「訓練する」に -ed を付けた過去分詞からできた形容詞で、語尾は /d/ と発音します。a trained nurse／worker／dog のように、練習や教育によって必要な技能・行動を身につけた対象に使います。experienced は経験の豊富さ、qualified は正式な資格を特に示すため、trained と同じとは限りません。
Trained comes from the past participle of train, meaning “to teach through instruction and practice.” The final -ed is pronounced /d/ because train ends in a voiced /n/ sound. Remember common combinations such as a trained nurse, a trained worker, and a trained dog: each has learned the skills or behavior required for a role. Trained emphasizes preparation through teaching and practice. Experienced focuses on knowledge gained by doing something over time, while qualified often implies that official requirements or credentials have been met.

trained の語源・成り立ち Etymology
trained は動詞 train の過去分詞形で、古フランス語 trainer「引っぱる・導く」を経て、ラテン語 trahere「引く」にさかのぼる。人や能力を望む方向へ“引いて形づくる”感覚から「訓練された」となり、関連語に attract, traction がある。
Trained is the past-participial form of train. The verb train came through Old French trainer, “to drag or draw,” ultimately from Latin trahere, “to pull or draw.” Its meaning developed from drawing something along or directing it toward a course to guiding a person’s abilities through instruction and practice. Trained consequently came to describe a person or animal shaped and prepared for a particular task. Traction and attract share the Latin root.
