Past Participle in Spanish
A past participle (el participio) is a very useful form of a verb which can function as an adjective, a predicative, or as a verb in conjunction with haber to form the perfect tenses.
Regular Past Participle Forms
To form the past participle of regular verbs, drop the infinitive ending (-ar, -er, -ir) and add -ado to the stem of -ar verbs and -ido to the stem of -er and -ir verbs. This is equivalent to adding -ed to many verbs in English.

Past Participle Uses
1. The Perfect Tenses
See the perfect tense references for a full explanation, examples, and irregulars. This is the most common use of the past participle and describes what a person has done in most cases.
There are perfect tenses for all tenses in Spanish (present perfect, past perfect, preterite perfect, future perfect, conditional perfect, present perfect subjunctive, past perfect subjunctive, and future perfect subjunctive.)

2. As an Adjective
Past participles that are used as adjectives must agree in gender and number to the nouns they modify.
3. As a Predicative Adjective
When used in conjunction with a linking verb (ser, estar, parecer), past participles act as predicative adjectives. Functioning as adjectives, they must agree with the nouns they modify in gender and number.
