If you meant realized, then its part of speech depends on its context. Here's how:
* Verb (past tense): When "realized" describes an action that happened in the past, it's a verb.
* Example: "I realized I had left my keys at home."
* Adjective: In rare cases, "realized" can be used as an adjective, meaning "made real or actual."
* Example: "This is a realized dream." (This usage is less common and often considered formal)
Important: To know the part of speech, you need to look at the sentence where the word is used.
