People who are dyslexic often have trouble pulling out the right sounds. It's not that they're not smart and don't know the meaning of words; it's a problem of getting the word with the right sound combination out. If a dyslexic is afraid that he'll mess up a word, he'll say an easier word, even though he knows a more difficult word. Dyslexics often say, "It's on the tip of my tongue," and what comes out may be a different word than intended. There was a little boy who was dyslexic and he was crossing the street with his dad and he saw lots of people jaywalking, and he looked up at his dad and he said, "Well, you know those Presbyterians ought to be more careful." He, of course, meant pedestrians, but the wrong word came out.
Spoken language is made up of different sounds. For instance, the word "mat," sounds like one glob of sound, but it's really made up of three different sounds: "mm," "aa" and "tuh." For people with dyslexia, these sounds are not as clear and crisp. According to Dr. Sally Shaywitz, "Dyslexia affects spoken language sometimes profoundly. It's not a problem with the meaning of words, it's a problem of getting the word with the right sound combination out. People who are dyslexic know the word they want to say, but when they have to attach sounds to it, something else may come out. Or they may stumble or speak around the word, or just not be glib. A dyslexic is not the person that's going to come in and give you this glib speech."
Despite intelligence, a good vocabulary, and great ideas, word retrieval snafus do happen. Keeping a sense of humor can be helpful to keep things in perspective. We've compiled a list of some of our favorites here:
