In the past few days I have heard the word "plethora" used a number of times on television broadcasts and am giggling about some of the pronunciations.
The word is pronounced with a short "e" and a long "0", but my 2 favourite attempts this week came out as "plethaaaaro" and "plathoroo". The first example was used by a television newscaster and it sounded very funny, a jarring surprise in the middle of an otherwise well delivered world news report.
It makes me wonder what words I am using regularly but not pronouncing properly. I would bet there are several and I hope no one is ever embarrassed to point my mistakes out to me.
