One letter has several qualities, position in the alphabet, shape, name etc but it has only one purpose: the letter represents a sound.
Each word has qualities also but it represents many ideas.
I had a slow difficult time learning to read but my teacher, Mrs. Platz, read stories to my class as a treat. I wanted those stories and worlds, hidden in code, created by all those words.
I write children’s books to create yummy worlds, fun stories, created by words of course but I play with words so they don’t seem like monsters to slow readers. A page from my book, Bears, is ‘The Bears’ big feet break Paul’s shoes, then their legs invaporste so it looks like they didn’t do it.’ Bearos is free as an eBook for a short time at Amazon. Have fun.  nancymauerman.com
