word mark and the brand name are basically the same thing, because the logo needs to be read by important people, so the graphic is not easy to pronounce. Just like a hook, you say what brand this graphic is going to be, and some of them are related, so it is directly called Nike. And more of them are called words. After the graphics are significant, they can also be called with a specific name.

however, brand names and commodity names are not the same thing, which needs no explanation.
