Bad news nearly always follows when dys- begins a word, and so it does here: dysgraphia is an inability to write coherently, either as a learning disorder or a result of brain damage or disease. The Greek roots mean "difficult writing." If you have dysgraphia, you might be able to write a little, but what you write won’t make much sense. Oddly, someone with dysgraphia may speak fine, since speaking and writing are controlled by different parts of the brain.
