I am unsure why this spelling error is so difficult, but it is one of the most common that I have seen.
I wish I had a quick cheat to remember which one is which (Maybe you do?) but I really don’t.
Desert is a noun, and a verb. You can desert someone (verb), or you can leave a person in the desert (noun).
Dessert is just something sweet that we all wish we could eat in excess and never pay the consequences.

Reminds me of a time we played Balderdash, a game where you all make up definitions, but only one is the correct one, then everyone tries to guess which one is right. The person reading all the definitions read one as “a desert composed primarily of goat cheese…”. Several of us at the table were soldiers, so it naturally progressed to ” Sir how much longer will we be marching through this desert of cheese? It’s building up on the men’s boots and their beginning to tire.”. Incidentally, “dessert” was spelled correctly, but the reader wasn’t the most literate person.
LOL too funny!
I try to remember that the two SS in dessert is what makes the word so yummy.
That is a great way to remember this! Thanks for sharing!
Dessert is the thing I want ssssssso bad 😉
One way I remember is that the pronunciation for these two words doesn’t fit English phonetics rules. Thus, ‘desert’ doesn’t make sense, but ‘dessert’ DOES, because it’s not English, it’s French.
Great idea Michael! Thanks for sharing!
