I think we were in grade school or high school when I used the word mishap pronouncing it thus: mi-shap. A classmate reacted but didn’t correct me outright, bless her soul. So I checked and found out it is supposed to be pronounced as mis-hap. Face palm.
When I was teaching my students snickered when I said stifle, pronouncing it with a long i. Like so:
They muttered loud enough for me to hear, steefle (the way one would pronounce steeple but with an f). I let them be. I hope by now they will have realized they were wrong.
I’ve been using the word prefix a lot and pronouncing it with a short “e”. What do you know, Carmina Villaroel, pronounced it with a long e in one of her commercials and I was stunned. Why didn’t they correct her, I wondered.
Then I checked in google and realized, it was I, yes, I, who had been mistaken all these years. FACE PALM.
