Wikipedia's pages are divided into namespace. Each namespace (except the main) has a prefix which appears with a colon at the start of page names.

All of these namespaces, except for Special, also have a corresponding Talk page for discussion. So for example you can discuss the starfish article at Talk:starfish, or talk about Wikipedia:Neutral point of view at Wikipedia talk:Neutral point of view. You can switch between the normal page and the talk page with the tabs at the top left.
