Mine actually is a form of dyslexia. I can usually read just fine, but when I write, type, or speak, it takes a lot of focus to get things to come out in the right order. If I’m distracted or in a hurry, letters get jumbled, similar-looking words get substituted in, the right words might come out in the wrong order, I might use the right base word but the wrong form such as “built” instead of “build”, or sometimes I just end up with extra letters where they don’t belong.
That last one is especially hard to explain if it happens while speaking.
It’s just ‘cuz we talk funny comin’ from WisCONsin and all, don’t cha’ know! ;)
