Recently, one of my answers was deleted from this question:
My best guess as to why is that it was considered a "duplicate" by the moderator. I'll agree that my answer was similar to that of another person, who referred to the prefixes of names of "organic substances."
My answer was more specific, insofar as it referred to counting carbon atoms, a term that the other person didn't use. That's a non-trivial additional point, at least to someone who has studied chemistry. I experienced a "light bulb" moment in my head when I looked up my own answer, after having read the other (and not benefited from it). Even if the content was similar, I believe that the greater clarity of my answer made it "distinct."
Can an answer that makes an important additional point be considered a duplicate? Or was my answer deleted for some other reason?
