A couple of years ago my son had a science teacher who would say larnyx instead of larynx and pharnyx instead of pharynx. She would also say alvioli instead of alveoli, making it sound like a pasta, my son said. Some kids in the class reading the text noticed she was mispronouncing the words. After a long time, they pointed out her mistake. I wonder how many of those kids will now pronounce the words incorrectly. (I home school now.)
