I have another question I've always wanted to ask. How do you spell words if you can't picture them in your mind?

Have you memorized that "pyramid" is spelled p-y-r-a-m-i-d and that for every word? How does it work for Chinese characters?

To answer my own question from a non aphantasia perspective the best I can describe it is that I conjure the picture of the word in my mind then I read each letter aloud.
