Okay kiddo, let me explain what Spanish orthography is.
Orthography is a big word that means the way we spell words. And Spanish orthography is all about how we spell words in the Spanish language.
In Spanish, we have 27 letters in the alphabet, just like in English. But we have some different letters too, like "ñ" which makes a sound like "nyuh" and "ll" which used to be its own letter but now it's treated as two letters.
Now, when we write words in Spanish, we have to follow some rules about which letters we use and where we put them. For example, we always write "t" before "a" and "o" but we write "d" before "e" and "i".
Also, sometimes a letter can make different sounds in different words. For example, the letter "c" can make the sound "k" like in "carro" or it can make the sound "s" like in "ciudad".
It's important to follow these rules so that we can read and write Spanish correctly, because if we make a mistake in the spelling, it can change the meaning of the word.
So that's basically what Spanish orthography is all about. Following rules about how to spell words in Spanish, using the right letters and putting them in the right places.
