I have to be fairly forgiving of people who learned the word by reading. When I was in high school, f'r example, I kept reading about this author named "go-eathee" who wrote Faust. Imagine my embarrassment in my last year of college when my Norwegian teacher was working a crossword puzzle (at lunchtime) and I contributed my knowledge to fill in one of the answers. She looked at me with appalled eyes and told me "It's pronounced "Gair-ta".

*shrug* At least she knew who I meant.
