この動詞の注意点

多くの時制で不規則です。表ごと覚えるのがいちばん確実です。 → 不規則動詞
覚えておきたい3つの基本形：do – did – done。
3人称単数で特別なつづり（-es, -ies）：does。 → 現在形（Simple Present）

太字と下線は語尾です。◆は規則から外れる形の印です。

よくある間違い

誤り Did you went to the party last night?

正しい Did you go to the party last night?

過去の疑問文で、didと動詞の両方を過去にしてしまう誤りがとても多く見られます。Did you went?ではなくDid you go?です。過去はdidが一回だけ表せば十分です。もう一つ、「昨日彼女に会ったことがある」のような感覚でI have seen her yesterdayと言うのも誤りです。yesterdayのような終わった時を表す語があれば過去形です。
