One of the things I struggle with as a writer is knowing what to explain to the reader. I don't know how much prior knowledge the reader has. To clarify, a "writer" is person who communicates through text. "Text," of course, being a combination of symbols to make up words. In English, we have 26 "letters."
26, or twenty-six, as it is sometimes written, is a number, which is different from letters. This particular number is less than 27 but greater than 25. To be clear, when I say "greater," I am describing the quantitative value. I am not suggesting that it is good or bad.
Anyway, here some things that some foolish people thought they needed to explain.
