is a funny word. First it can be pronounced with the accent on the first or second syllable. (I prefer the first)I think the first time I heard the word, it was uttered by Howard Cosell on Monday Night Football. Howard was good with the words.
I bet many use this word incorrectly.
The correct meaning of the word plethora is
embarrassment of riches
Most use it to mean many or a lot. For example, they say, “A plethora of ideas were generated at the meeting.” I think they mean many, not too many.
Are you using plethora correctly?
