Why is it a dragon?

I am sure many people are confused as to why two things like a wurm and a western dragon can be classified into one big race known as 'dragon'. I am here to try to explain how we know that it is a dragon.

• Most dragons have at least one or two reptile-like traits to them. Things like scales, snake-tails, snake heads, reptilian bodies, and so on all apply. Other things to note is if the story the dragon is in related it to a snake or other form of reptile, be it through behavior or appearance.
• Most-all dragons have, had, or will have the ability to fly. For instance, some Chinese dragons can not fly, but that is because they are too young and are not mature enough to do so. Note that not all dragons have wings, and they can still fly.
• Close connections with water is another major trait of the dragons. The dragon might live in the water, spew water, or have emerged from some sort of nearby water source. You might also have to look for the location of the dragon's lair.
• Look for supernatural powers such as magic or super-strength. The power does not necessarily have to be anything amazing, but it does have to be something that most things can not do. For instance, flying without wings, or the ability to move things with their minds.
• Weaponry that comes from their mouth. This includes spitting fire, water, and poison. Some people say ice as well, but I have found few dragons with this trait.

Secondary Traits - usually the dragon will have these, but it might not be specified or elaborated upon. At other times, the dragon might not have these.

• Some dragons are connected to the weather. This meaning that they have powers over the weather and perhaps the ability to create storms. The most common ability is that of rain or droughts.
• Connection with birds is somewhat common among dragons. Some dragons share traits with birds, namely feather wings or feathers in general. Some even have bird's feet.
• Look and see what the dragon is doing as its primary job. Most dragons guard something, like treasure, maidens, secrets, towns, forests, and so on and so forth. Sometimes these jobs are assigned to them by gods or goddesses while others appoint themselves.
• Dragons are usually creatures of power. They usually have high ranks, are gods, or are closely connected to a god or goddess of some kind. Usually they are servants to people of power as well, but more commonly to gods.
