Okay kiddo, so when we talk about the word "disc," it's important we know how to spell it correctly.
"D-I-S-C" is the right way to spell it. Each letter stands for a sound we make when we say the word.
Let's break it down. The first letter, "D," sounds like the first sound in the word "dog." The second letter, "I," sounds like the "ihh" sound in "big." The third letter, "S," sounds like the sound you make when you try to be sneaky by saying "ssshhh." The fourth letter, "C," can be a little tricky, because sometimes it sounds like "k" and sometimes it sounds like "s." In the word "disc," it sounds like "s."
So, when we put all the letters together, we get "D-I-S-C," which spells "disc." And that's how we write it on paper, on our computer, or anywhere else we need to use the word.
