I'm Speechless Word of the Day
aphasia

If you can remember that the combining form -phasia (from Greek for "speak") denotes speech disorders, you have a handy box for a number of things that can go wrong with vocalization. Aphasia is an inability to produce speech owing to disease or injury; dysphasia is the impairment of such ability. All other phasias are rarer and more obscure.
