覚え方のコツ Memory Tip
undertake「重要な仕事・責任を引き受ける」の不規則過去形で、take→took と同じく undertake→undertook と変化する。発音も語末が take /teɪk/ から took /tʊk/ に変わる。undertook a reform、study、responsibility のように、重大な計画への着手や責任の引受けに使う。
Link undertook directly to the familiar irregular change take–took: undertake becomes undertook in the past tense. The final sound changes from the vowel in take /teɪk/ to that in took /tʊk/. The under- element does not mean that the action happened physically below something; the whole verb means accepting or beginning serious work. Remember formal combinations such as undertook a reform, undertook a study, and undertook responsibility. These usually describe a substantial commitment, not an ordinary momentary action.

undertook の語源・成り立ち Etymology
古英語の接頭辞 under-（下に・引き受けて）と古ノルド語由来の take（取る）の複合動詞 undertake の過去形。「自分の下に取り込む」が原義で、責任を引き受ける意味に発展した。関連語: undertaker（葬儀屋）、undertaking（事業）。
Undertook is the irregular past tense of undertake, formed historically from under and take. The verb developed in Middle English with the sense of taking something upon oneself, including a duty, promise, or enterprise. Its past-tense pattern follows take–took rather than adding -ed. The related nouns undertaking and undertaker developed from the same verb, although undertaker later acquired the specialized meaning of a funeral director.
