I had the same feeling, so I began to read https://www.forth.com/starting-forth/1-forth-stacks-dictiona... with gforth installed with apt. And made few exercises to manipulate the stack with some words and get a grasp on it. Now I saw how it works, I came back to my imperative languages and won't come back to it. IMO my skills in forth are not really enough to see the distinction between any implementation of forth, so the first one I stumbled upon was ok.
