The word "invigorated" is derived from the verb "invigorate," which itself is made up of the root word "vigor" and the prefix "in-".
Here's the breakdown:
* Root: vigor (meaning strength or energy)
* Prefix: in- (meaning "to put in" or "to make")
Therefore, "invigorated" is the past participle of the verb "invigorate," meaning "to give vigor to."
