What part of speech is caused?

"Caused" can be a few different parts of speech, depending on its context:

* Verb: This is the most common use. It means to bring about something, to be the reason for something happening.

* Example: "The storm caused the power outage."

* Past participle: This form of the verb can be used as an adjective or part of a verb phrase.

* Example: "The caused damage was extensive." (adjective)

* Example: "The damage has been caused by the storm." (part of a verb phrase)

So, without context, it's impossible to say for sure what part of speech "caused" is. You need to look at the sentence it's used in to determine its function.
