Questions about past participle forms of verbs.
The past participle is one of the main inflected forms of the English verb. It has several uses, which include forming constructions in the passive voice and in the perfect aspect or anterior tenses (such as the pluperfect or past perfect).
In many cases, it is identical to the simple past form (including for all regular verbs, which use the suffix -ed to form the past participle and the simple past). But there are also many commonly used irregular verbs where these two forms are distinct, such as to go, for which the past tense is went and the past participle is gone.
