What is appropriate usage of "numerator", "denominator", and "nominator" to refer to parts of a fraction?
I'm posting this question and answer here because I had little luck finding a clear answer through Google. I realize that it's not really mathematics, but I think it's worth mentioning as an educational issue.
Ideally, the question at English.stackexchange would address this completely, however they have closed it with the reason: "you can just look it up". I agree that this is possible, but I don't think that reveals the consensus. I wanted to allow for more opinions to be expressed. (Below, I argue that "nominator" should be discouraged.)
