Are there any words that you pronounce in a way that seems weird to most people?
I've always pronounced the word "Southern" to rhyme with howthurn. I know most people say it like "suthurn" instead. I didn't realize that the way I pronounce it is considered weird until recently!
Et cetera is similarly "et ketera", unless you're using Italianate ecclesiastical pronunciation. Then it's "et chetera", hard ch like church in English.
Only bit at uni and that was over two decades ago. I only use what I learned to produce technically correct yet insufferable Latin pronunciations to lovingly harass friends and family.
