Here's why:
* Verb: The base form of the word is "examine," which is an action word.
* Past Participle: The past participle form is used in several ways:
* With "have" or "has" to form the perfect tenses: "They have examined the evidence."
* As an adjective: "The examined evidence was inconclusive."
* In passive voice constructions: "The evidence was examined by the police."
