To get a better idea of the language let's look at it in more detail. You would start with the file header. That's just the title at the top of your file which identifies it as a VRML file. The browser ignores all comments except those on that first 'header' line, which 'sets the scene' for your scene. Next, you list objects in your file known as nodes.
Nodes are the basic building blocks of scenes listed as a scene graph.
Each node has fields that have specific information about that node. For example, you could have a Material node that describes the outside of an object and you could have a field within that node which could describe reflective surface of the object. Nodes can have order, and that order can also affect the objects in the scene. Another field could explain colours in the nodes. As you can see, VRML is written in a sort of En-glish text which describes the scene.
