Regular and Irregular Past Participles
In the past perfect tense, you always use the past participle form of the main verb after had. There are two types of verbs: regular and irregular. Knowing their past participle forms is essential to form sentences correctly.
Regular Verbs
Regular verbs form the past participle by adding -ed (or -d if the verb ends in “e”).
Examples:

|---|---|---|
| work | worked | She had worked there for years. |
| clean | cleaned | He had cleaned the kitchen before dinner. |

| study | studied | I had studied French before moving. |
| call | called | She had called me earlier. |
| watch | watched | We had watched the film already. |
Irregular Verbs
Irregular verbs do not follow the -ed rule, so you must memorize their past participle forms.
Examples:
| Base Verb | Past Participle | Example Sentence |
|---|---|---|
| go | gone | She had gone home before I arrived. |
| eat | eaten | I had eaten before the meeting started. |
| see | seen | They had seen the news already. |
