Hello there!
The word "dessert" or even "desert" would be hard to pronounce because first, they sound very similar. And not only that, but if you to try to teach some one English, that would most liley be there hardest word (or at least one of them). This word does contain different meanings and not only that, they sound different so this is 2 ways why people sure do get confused with these both.
