Is this where we get dessert? Is there something inherent in our word for the sweets after a meal that implies a worthiness for it? Certainly in my family, dessert has always been colored this way. Either in that one deserves dessert for some reason or that one doesn’t deserve it but you’ll be “bad” and get it anyway.
I guess technically dessert must come from the French and the English use pudding for dessert so we don’t get it from them but there is something so apt about the way these meaning intersect. The moralism of dessert mixing with desert, but not desert like the landscape without water, but desert, pronounced the same as the American dessert, is appropriate for our American roots, our Puritanical heritage that calculates everything to deserving.
