Okay, kiddo, let me explain what heterography means. You know how there are some words that sound the same, but are spelled differently? For example, "there," "their," and "they're." These words have different meanings and are spelled differently, even though they sound the same. This is called heterography.
Heterography is when two words sound the same but are spelled differently and have different meanings. It's kind of like having twin brothers with different names and personalities. Even though they look the same, they are different people.
Now, let's go back to the example I gave earlier. "There" means a place, "their" means belonging to someone, and "they're" means "they are." Even though they all sound the same, they are different words and mean different things.
Heterography can be tricky because you have to remember the different spellings and meanings of words that sound the same. But it’s also kind of cool because it shows the tricks of the English language, right?
