I was just typing a sentence that included the phrase “Merry Christmas” and I wondered why I was capitalizing “Merry” in the middle of a sentence. It seems to me that that’s how it’s usually presented. Shouldn’t it begin with a lowercase “m”? Yes it should. That is what I’ve decided. “Quixotic” on the other hand should always be capitalized, in the same way that “Capraesque” is capitalized.
