Listed specifically in the constitution. For example, Article 1 Section 8 of the USC lists all the enumerated powers bestowed upon Congress. These include, but are not limited to, the right to
• Impose taxes and tariffs upon U.S. goods and imports.
• Regulate how much our money is worth, as well as foreign coin and such sort.
• Declare War.
Now, one of the powers is, and I quote;
"Make all Laws which shall be necessary and proper for carrying into Execution the foregoing Powers, and all other Powers vested by this Constitution in the Government of the United States, or in any Department or Officer thereof."
Now, these are the unenumerated (or implied) powers. For example,the Constitution doesn't say you can have to buy at so-and-so grocery store. But it is implied in the fact that we have free will.
Another, less ludicrous example, would be the right to travel. It isn't stated, but it is implied.
Thus, an enumerated power is a power bestowed upon Congress that is explicitly listed in the U.S Constitution. Hope I could be of help! <3
