Right. But I think most people that stutter have a root word in which the stuttering gets extended to other words and sounds. For me, my stuttering started with M words because a woman around my age I knew with a name that started with M would be really friendly with me every time I saw her. And because I tend to be a sensitive person, I got intimidated by emotional connection with others. So at that time I felt uncomfortable by her so began stuttering on words that start with M. From there it progressed to other sounds. Now I’m retracing my steps to understand how my thinking led to stuttering. At least for me, M words were my root. It’s largely psychological for myself.
