Okay, kiddo. So, imagine you're trying to learn how to read and write. You know what letters look like- like the letter "A" or "B". But sometimes it's hard to remember what sound each letter makes.
Now, think about another way of writing that is different from the letters we use. This way uses little pictures or symbols to represent different sounds. So instead of the letter "A", you would have a symbol that looks like a mouth open wide to make the "A" sound.
This way of writing is called a featural writing system. It helps people who speak different languages and have different alphabets to communicate with each other easily because everyone can use the same symbols to represent the same sounds.
It's like using emojis to send messages to your friends on your phone. Instead of typing out words, you can just use a picture of a smiley face to show that you're happy!
So, a featural writing system uses symbols to represent sounds instead of letters. It's like using little pictures instead of words to write a message.
