I agree with you that we appoint a value to a feared word. As you already pointed out, a value of fear or distrust that we won't say it correctly or can't say and might get stuck. So one could say that fear it not the problem, but appointing the value is the real problem of the stutter disorder. You seem very intelligible. You're a wealth of wisdom! Could you provide strategies to unlearn appointing a value of low ability to pronounce feared words? For me it's okay if you write much, don't worry if it becomes too long.
