Quando o Past Simple e o Past Participle não terminam em –ed (exemplo: I saw; I have seen), o verbo é irregular.

Com alguns verbos irregulares, todas as três formas (infinitive, past simple e past participle) são as mesmas. Exemplo:

Don’t hit her. (infinitive)

Somebody hit me as I came into the car. (past simple).

Have you ever hit anybody in your life? (past participle – present perfect)

Jenny was hit on the arm by a Stone. (past participle – passive)

Com outros verbos irregulars, o past simple é o mesmo que o past participle, porém diferente do infinitive. É o caso de tell à told:

Could you tell me where you were? (infinitive).

She told me she was in London last week. (past simple).

Have you told anybody about your new girlfriend? (past participle – present perfect)

I was told to stay here for a while. (past participle – passive)

Enfim, com outros, todas as três formas são diferentes…estes são os piores, mas difíceis de lembrar…geram sempre dúvida! Exemplo (wake/woke/woken): 

I’ll wake you up. (infinitive).

I woke up in the middle of the night. (past simple)

The kids have woken up. (past participle – present perfect)

She was woken up by a loud noise (past participle – passive).
