Here's how to break it down:
* Veritable: This word means "true" or "genuine." It's often used to emphasize that something is not just any ordinary example, but a real, genuine one.
* Plethora: This word means "a large or excessive amount of something."
So, when you say "veritable plethora," you are emphasizing that the abundance is not just a lot, but truly a huge and overflowing amount.
Example: "The library had a veritable plethora of books on ancient history, enough to satisfy even the most dedicated scholar."
