Here's why:
* Past Participle: A past participle is a form of a verb that is used to form perfect tenses (e.g., present perfect, past perfect) and passive voice.
* Open Past Participle: This refers to the past participle used in its "open" form, meaning it functions as an adjective or part of a verb phrase.
For example:
* Spoken words: (adjective)
* She has spoken to the manager. (past perfect tense)
* The decision was spoken about by the committee. (passive voice)
