Definition

1. Noun:
   • A verb form that typically ends in "-ed," "-d," "-t," "-en," or "-n" and is used in perfect tenses (e.g., "has walked," "had seen") and the passive voice (e.g., "was taken," "are written"). It expresses a completed action or a state resulting from an action.

Usage

The past participle is not used as a standalone verb. It must be used with an auxiliary (helping) verb. * With "have"/"has"/"had" to form the perfect tenses (present perfect, past perfect, future perfect). * With "be"/"am"/"is"/"are"/"was"/"were" to form the passive voice.
