Your YouTube Mom is back to point out some common words that you might be saying wrong.
I can promise you that forte is pronounced "for-tay" and not fort. It's an Italian word used in music meaning 'loud'. So the idiom "that's my forte" is using the correct pronunciation, which you noted as wrong.
For those who think only Utahns pronounce words wrong…sorry to say, every region has unique regional dialects and pronunciations. Fer sure, :) Utahns have their fair share, but I've lived all over the country and have had fun learning that every area has some fun, unique ways of saying things. Vive la difference!
