The past simple expresses actions, states, or events that started and finished at a definite time in the past. Regular verbs mark this past meaning by adding -ed or -d to their base form. Irregular verbs mark the past through historical vowel changes, consonant shifts, or unchanged forms rather than adding -ed.
