受けた
解説 Definition
undergone は undergo「受ける・経験する」の過去分詞です。人や物が手術、検査、訓練、修理、変化などの過程を経たことを表します。
Undergone is the past participle of undergo. It indicates that someone or something has experienced or been subjected to a process such as surgery, testing, training, repair, or significant change.
使い方 Usage
- has／have／had undergone の完了形でよく使います。undergone は過去形ではなく、過去分詞です。 Undergone commonly follows has, have, or had in perfect forms. It is the past participle, not the simple past form.
- undergone surgery／testing／repairs／changes のように、受けた処置や変化を前置詞なしで続けます。 Place the process directly after undergone, without a preposition: undergone surgery, testing, repairs, or changes.
覚え方のコツ Memory Tip
go–went–gone と同じ変化を保ち、undergo–underwent–undergone となります。人や建物がある過程を通り抜け、その後の状態になる像と結び付けましょう。
Link the forms to go–went–gone: undergo–underwent–undergone. Picture a person or building passing through a process and emerging afterward.
例文
The building has undergone major repairs.
その建物は大規模な修理を受けました。
She has undergone several medical tests.
彼女はいくつかの医学検査を受けました。
The system had undergone many changes before release.
そのシステムは公開前に多くの変更を経ていました。

undergone の語源・成り立ち Etymology
undergone は undergo の過去分詞で、古英語 undergān に由来し、under「下を」+ go「行く」から成ります。もとは「下を通る」ですが、経験や試練を通り抜ける感覚から「受ける・経験する」の意味になりました。関連語は go, undergo。
Undergone is the past participle of undergo, formed from under and go. Undergo continues Old English undergān, originally associated with going beneath or passing through something. Its meaning developed toward enduring, experiencing, or being subjected to a process. The participle follows the inherited irregular pattern of go: just as go forms gone, undergo forms undergone, while its simple past is underwent.
