I have been spelling the word "curiosity" with a u, "curiousity," my whole life, and only today was Chrome's spellcheck bold enough to highlight my lifelong error. I have two questions:
- The root word is curious. How or why has the quality of being curious come to be spelled without its u? Or is it the word curious that is unique, and both words were derived from a word with no u, like curio?
- Since I have spelled the word this way my whole life and none of my English teachers/professors ever crossed out this "misspelling," is it not technically incorrect, just discouraged? Or perhaps it is archaic, which is why I could only find it defined in a legal dictionary with a capital "C:" Curiousity, not curiousity.
