Severe literacy difficulties due to lack of inability to memorize letter sequences for words leading to spelling almost exclusively via sounding out words. Further, because it takes so much concentration and conscious thought to spell the words, and to try reread them, it interferes with organization of the words into proper sentence structure. So it comes out with grammar that is even worse than verbal conversation level (verbal conversation grammar being less formal than written, yes even when spoken by you
).
One of my kids writes a lot like this. He busted his ass to be able to write that well. *shrug* He has a sharp memory about some things but letters and numbers, they just don't stick.
Sometimes for similar reasons.
