I just have a quick question-

I just have a quick question- What is stuttering? Does it always have to be like “s-s-so-som-s-somebody t-told me” or could it be somewhat like “somebory tod me” or repeating a word over and over while you try to think of what to say next, like “and then he like- like he like- like- like he said that-“? As well as something that usually only happens when you’re kind of spaced out or really excited? I mean this as is it technically a clinical stutter or just a natural thing that most people experience
