It’s that damn “au” that gets everyone. When people take a stab at my last name after reading it almost never think it is 2 syllables. On the off chance they do think it is 2, I always get an incorrect “au” sound.
When I was student teaching, I introduced myself to classes by telling them that my last name rhymed with “Audi”
I had to modify the statement and make sure that I let the students know that I meant the automaker after a group of sixth graders asked if I meant “the belly button.”
