Также существуют неправильные глаголы (irregular verbs), к которым не ставится окончание ed, вместо это слово меняется целиком.

go -> went (goed – ошибка)

У неправильных глаголов существует три формы: первая (начальная), вторая (Past Simple) и третья (Past participle- нужна чтобы сделать Perfect или чтобы сделать прилагательные из глагола)

Для Past Simple нужна вторая форма из таблицы:

go -> went -> gone make -> made -> made
